How to Prepare for the FRCOphth Part 2 Written and FRCS Ophthalmology Part 2 Written: A Complete Step-by-Step Guide

Key Takeaways (At a Glance)

• The FRCOphth Part 2 Written tests your ability to apply clinical ophthalmology to recognise disease, interpret investigations, and make management decisions, not basic science recall. If you prepared for Part 1 through textbook memorisation, that method does not transfer here.
• The FRCOphth Part 2 Written is two papers of 90 SBA MCQs each, 180 questions total, sat on the same day. The FRCS Ophthalmology Part 2 Written is a single paper of 180 SBA MCQs over approximately 2.5 hours.
• The RCOphth states directly that candidates are unlikely to pass Part 2 Written without significant clinical training in ophthalmology. This exam assumes you have been seeing patients, preparation without real clinical exposure has a ceiling.
• You do not need the Refraction Certificate before sitting Part 2 Written. The two can be taken in any order after passing Part 1.
• The FRCOphth Part 2 Written permits a maximum of four attempts, and a pass is valid for seven calendar years from the date achieved.
• A structured six-week preparation plan, built around the high-yield clinical subspecialties rather than the full textbook, is what separates candidates who pass comfortably from those who pass narrowly or not at all.
• The FRCS Ophthalmology Part 2 Written is a single uninterrupted paper of 180 questions over approximately 2.5 hours. Candidates preparing for this exam must train for the endurance demand of the single sitting, the FRCOphth two-paper pacing strategy does not transfer.

You passed Part 1. The basic sciences are behind you.

The FRCOphth Part 2 Written and FRCS Ophthalmology Part 2 Written ask a different question entirely: not what do you know about optics and anatomy, but can you apply clinical ophthalmology knowledge to recognise disease, interpret investigations, and reach the correct management decision, all within a single-best-answer format and a fixed time limit.

This guide walks through exactly what each exam tests, how the formats differ, and how to build a preparation plan that targets the curriculum efficiently rather than attempting to revise everything equally.

If you prepared for Part 1 by working through optics and anatomy textbooks systematically, that approach will not transfer directly to Part 2 Written. The questions are clinical scenarios: a patient presents with specific findings, and you must identify the diagnosis, the correct investigation, or the appropriate management step. Effective preparation for this exam requires clinical pattern recognition built through exposure to high-yield subspecialty topics, supported by question practice that mirrors the single-best-answer format, rather than linear textbook revision. 

What the FRCOphth Part 2 Written Actually Tests (And Why Part 1 Preparation Does Not Transfer)

Applied Clinical Knowledge, Not Basic Sciences

Part 1 tested optics, anatomy, physiology, and basic science. Part 2 Written tests something fundamentally different: your ability to apply clinical ophthalmology knowledge across the full curriculum, including disease recognition, interpretation of investigations, and clinical decision-making.

According to the Royal College of Ophthalmologists, the Part 2 Written exam is aimed at trainees in years four to seven of Ophthalmic Specialist Training, and candidates are unlikely to pass without significant clinical training in ophthalmology. This is not a knowledge-recall exam you can pass through textbook memorisation alone. It assumes you have been seeing patients.

How the FRCOphth Part 2 Written and FRCS Ophthalmology Part 2 Written Differ in Format

FRCOphth Part 2 Written: Two Papers, Same Day

The FRCOphth Part 2 Written examination consists of 180 single-best-answer multiple-choice questions, split into two papers of 90 questions each, taken on the same day. According to the RCOphth, candidates sit this as an online proctored examination, taken at a location of their choosing rather than at a physical exam centre.

The exam is held twice a year, in June and November, candidates should confirm current sitting dates directly on the RCOphth examinations calendar Candidates are permitted a maximum of four attempts to pass the Part 2 FRCOphth Written component, with attempts prior to August 2014 not counted. A pass is valid for seven calendar years from the date it is achieved.

FRCS Ophthalmology Part 2 Written: One Extended Paper

The FRCS Ophthalmology Part 2 Written examination, administered by the Royal College of Physicians and Surgeons of Glasgow, takes a different format: a single paper of 180 single-best-answer questions, sat over approximately 2.5 hours, rather than split across two separate papers.

According to the RCPSG, the Part 2 examination tests knowledge of ophthalmic medicine and surgery alongside general medicine and neurology relevant to ophthalmic practice, forming the second stage of the FRCS Ophthalmology assessment after Part 1.

This means FRCS Ophthalmology Part 2 Written candidates must ensure their preparation includes general medicine and neurology content that FRCOphth candidates do not need to prioritise. Candidates who prepare using FRCOphth-focused resources alone without covering these additional domains will be underprepared for a proportion of the paper.

Why the Difference in Structure Matters for Your Preparation

Both exams draw on a substantial overlap in clinical syllabus. The practical difference is pacing and endurance. The FRCOphth format gives you two separate blocks of 90 questions, which allows a natural reset point partway through the day. The FRCS format is a single continuous 180-question paper, which places more emphasis on sustained concentration and consistent pacing across the full sitting.

If you are preparing for the FRCS Ophthalmology Part 2 Written specifically, practising full-length 180-question mock papers in one sitting, rather than splitting your practice into shorter blocks, will better prepare you for the actual exam-day endurance demand.

Where the FRCOphth Part 2 Written Fits in Your Pathway, and What Comes Before It

You Do Not Need the Refraction Certificate First

A common misconception among first-time candidates is that the Refraction Certificate must be passed before Part 2 Written. This is incorrect. According to the RCOphth, candidates do not need to have passed the Refraction Certificate examination in order to sit the Part 2 Written. The two can be taken in any order, provided Part 1 has already been passed.

This matters for your planning. If your clinic access for refraction practice is limited at a particular point in your training, but you have strong clinical exposure for Part 2 Written content, there is no rule preventing you from sitting Part 2 Written first and the Refraction Certificate later, or vice versa. For a full guide on when to sit the Refraction Certificate and how to plan it around Part 2 Written, see our [FRCOphth Refraction Certificate timing guide].

The Full Sequence to Part 2 Oral

To become eligible for the Part 2 Oral examination, you must have passed all three of: Part 1 Written, the Refraction Certificate, and Part 2 Written. Part 2 Written and the Refraction Certificate are interchangeable in order, but both are mandatory gates before the Part 2 Oral becomes accessible.

For OST trainees, the RCOphth requires that the Part 2 Written and Part 2 Oral are both passed by the end of year seven of specialist training. A pass achieved after completion of the training programme is not considered towards the award of a Certificate of Completion of Training, so timing this exam appropriately within your training years matters significantly. OST trainees should confirm their specific timeline with their programme director and the RCOphth if they are approaching the end of year seven with either component outstanding.

The High-Yield Clinical Curriculum: What to Prioritise

The Subspecialty Areas That Carry the Most Weight

Both the FRCOphth and FRCS Ophthalmology Part 2 Written examinations draw questions from across the full UK ophthalmology curriculum. Attempting to revise every subspecialty with equal depth is an inefficient use of preparation time. The following subspecialty areas carry significant question weight across both examinations, based on PrepMedico’s faculty review of the curriculum and candidate feedback across multiple cohorts:

• Retina and medical retina, including retinal vascular disease, macular disorders, diabetic retinopathy, and retinal detachment
• Neuro-ophthalmology, including optic neuropathies, visual pathway lesions, and pupillary abnormalities
• Cornea, external eye disease, and cataract, including corneal infections, dystrophies, and surgical principles
• Paediatric ophthalmology, strabismus, and orbital pathology
• Glaucoma and investigation interpretation, including OCT and visual field analysis
• Uveitis, ocular oncology, and systemic medicine relevant to ophthalmology

Investigation Interpretation Is Tested Directly

A significant proportion of Part 2 Written questions test your ability to interpret investigations directly: OCT scans, visual field printouts, fundus photographs, and similar clinical data presented as part of the question stem. This is a different skill from recalling disease facts. It requires deliberate practice interpreting investigation images under exam-style conditions, not just reading about the underlying pathology. The RCOphth publishes sample MCQs for the Part 2 Written examination, which give a useful indication of how investigation interpretation is framed within the question format.

If your clinical exposure has been heavier in some subspecialties than others, structured question bank practice across all six core areas, with particular attention to investigation interpretation questions, helps close gaps before exam day.

How to Build Your Preparation Plan: A Six-Week Framework

The Preparation Sequence

A structured six-week preparation timeline, working through the curriculum systematically rather than reactively, is an effective framework for both exams:

1. Weeks 1 to 2: Retina, medical retina, and neuro-ophthalmology. These two subspecialties carry significant clinical weight and benefit from being covered early, giving time to revisit weaker areas before the exam.
2. Weeks 3 to 4: Cornea, external eye, cataract, paediatric ophthalmology, and strabismus. Covering surgical fundamentals and common paediatric exam scenarios in the middle of your preparation allows consolidation before the final stretch.
3. Weeks 5 to 6: Glaucoma, investigation interpretation, uveitis, ocular oncology, and systemic medicine. Finish with the areas most dependent on investigation interpretation skill, since this benefits from being fresh closer to the exam date.
4. Throughout: structured SBA question bank practice. Single-best-answer practice questions, reflecting the actual exam pattern, should run in parallel with topic revision from week one, not be left until the final fortnight.
5. Final week: a full-length mock examination under timed conditions. A complete mock paper, replicating the difficulty and format of the actual exam, reveals whether your pacing and accuracy hold up under genuine time pressure before exam day rather than during it.

This is exactly the structure PrepMedico’s FRCOphth & FRCS Ophthalmology Part 2 Written course follows: six weekly three-hour lectures covering the high-yield clinical subspecialties in this sequence, supported by SBA question bank access throughout, and a full mock examination in the final phase.

Why Question Practice Should Start Early, Not Late

A common preparation error is treating question banks as a final-stage revision tool, used only in the last two weeks before the exam. This wastes the diagnostic value of question practice.

Why Start Question Bank Practice in Week One, Not Week Five

Working through SBA questions early reveals which subspecialties need more attention while there is still time to address the gap, rather than only confirming weaknesses you no longer have time to fix.

Common Preparation Mistakes for Part 2 Written

Treating It Like a Part 1 Revision Exercise

Candidates who passed Part 1 through systematic textbook revision sometimes apply the same approach to Part 2 Written, expecting basic science recall questions. The exam tests clinical application instead. Revising disease facts without practising how those facts are tested in a clinical scenario format leaves a gap between what you know and what you can demonstrate under exam conditions.

Ignoring the FRCS-Specific Single Paper Format

Candidates preparing for the FRCS Ophthalmology Part 2 Written sometimes train using the FRCOphth two-paper structure as their model, without adjusting for the longer, single continuous paper format. The pacing strategy that works for two 90-question blocks with a break in between does not directly transfer to a single uninterrupted 180-question sitting. Practise the format you are actually sitting.

Underestimating Investigation Interpretation Questions

Candidates who focus preparation entirely on disease knowledge, without dedicating specific practice time to interpreting OCT scans, visual fields, and fundus images under exam conditions, are often caught off-guard by how frequently these question types appear. This is a distinct skill that benefits from targeted practice, not incidental exposure.

PrepMedico’s SBA question bank includes investigation interpretation questions with OCT, visual field, and fundus image stems, the same format used in both exams.

For Candidates Preparing Outside UK Clinical Training

International graduates and IMGs are eligible to sit both the FRCOphth and FRCS Ophthalmology Part 2 Written examinations, provided Part 1 has been passed. UK-based training is not a requirement. However, candidates preparing outside the UK system need to ensure their clinical exposure matches the breadth and depth expected by the UK ophthalmology curriculum, particularly around general ophthalmic conditions, emergency presentations, and the surgical principles tested across subspecialty questions. For a full overview of eligibility and the broader FRCOphth pathway, see our complete guide to the FRCOphth exam.

PrepMedico’s Part 2 Written course is delivered entirely online and is designed to ensure international candidates cover the UK curriculum systematically, regardless of the clinical environment they are currently training in. The lecture series and SBA question bank are built around the UK ophthalmology curriculum, not a country-specific adaptation of it.

After You Pass the FRCOphth Part 2 Written: What Comes Next

A pass in either the FRCOphth or FRCS Ophthalmology Part 2 Written examination clears one of the two remaining gates before the Part 2 Oral, alongside the Refraction Certificate. Once both are confirmed, you become eligible to apply for the Part 2 Oral examination, which assesses clinical judgement, investigation interpretation, and patient management through structured viva and OSCE stations.

One practical point on timing: once Part 2 Written and the Refraction Certificate are both confirmed passed, submit your Part 2 Oral application without delay. Application windows for the oral examination are fixed and fill. Candidates who wait to apply after confirming both gates are cleared sometimes miss the next available sitting by days. Check the RCOphth or RCSEd/RCSGlasg examination calendar and submit as soon as eligibility is confirmed.

The skills tested in Part 2 Written and the skills tested in Part 2 Oral are related but not identical. Strong written exam performance demonstrates that you know the clinical material. The oral examination then tests whether you can organise and communicate that same knowledge under direct observation, which is why preparation for the two stages, although connected, requires a different approach once you reach that point in your pathway.

Conclusion

Part 2 Written is not a harder version of Part 1. It is a different exam entirely, testing clinical application rather than basic sciences, and it rewards candidates who prepare with that distinction in mind from the outset.

Build your preparation around the high-yield subspecialty areas. Start question bank practice early, not in the final fortnight. If you are sitting the FRCS Ophthalmology format, train for the single 180-question paper specifically, not for the FRCOphth two-paper structure. Finish with a full-length timed mock before exam day.

The candidates who pass comfortably are not necessarily the ones who read the most. They are the ones who matched their preparation method to what the exam actually tests.
