RES Question Banks Compared (2026): Paid and Free Options

There are plenty of RES practice questions online. The harder part is working out which question bank is actually useful for the way you study.

Some are completely free. Some charge monthly. Others sell fixed access periods. Published question counts range from a few hundred to more than 4,000, but those numbers are not always directly comparable.

We checked the public product information available on 16 September 2026. Where a provider did not state something on the pages we reviewed, the tables below say not stated. Where a provider's own pages gave conflicting figures, we show the conflict rather than choosing one.

Disclosure: ConfirmPass publishes this comparison and is one of the products included. We applied the same comparison fields to every provider, used provider-published information for product claims, and have shown inconsistencies where we found them rather than resolving them in a provider's favour.

How to use this comparison

Question count is useful, but it should not be the only thing you compare.

A bank with 4,000 questions is not automatically more useful to you than one with 1,500. Providers may count questions differently, some include case-study questions in the total, and some publish different totals on different pages.

Before paying, look at five things:

1. Can you try the questions first?

2. Are explanations available on the questions you will actually practise?

3. Is there enough case-study practice for the way you are revising?

4. Does the product renew automatically, or are you buying a fixed period of access?

5. Does the product help you decide what to practise next, or does it simply give you a large bank to work through?

Question counts are not always comparable

Several providers publish totals that do not reconcile across their own pages.

RESPrep currently has public pages stating 2,200+, 2,600+ and 2,653+ questions.

How To Pass RES advertises 2,000 MCQs, but the same page itemises 758 questions for Paper 1 and 721 for Paper 2, a total of 1,479.

SGExamReady publishes both 1,500+ and 2,000+ figures.

That does not prove anything is wrong with the underlying bank. Different pages may be counting different pools, or one page may simply have been updated later than another. It does mean the figures should be treated as provider-published counts rather than perfectly comparable measurements.

ConfirmPass is the exception in this table because the current bank count is known directly: 2,694 questions.

There are substantial free RES question banks

You do not have to pay before doing meaningful practice.

The Edmund Ee RES Revision Portal currently advertises 1,850+ free MCQs for Paper 1 and Paper 2, 10 case studies and an official-format mock.

RESPaper.sg advertises more than 1,100 questions and 194 case studies as completely free resources.

OpenExamPrep has separate Paper 1 and Paper 2 banks with more than 100 questions each, with no registration or credit card required.

NAVIS RES Exam Revision is a free app whose App Store listing describes hundreds of questions across Paper 1, Paper 2 and case-study practice.

Among paid products, several also let you test at least part of the experience before buying. How To Pass RES has an ongoing free tier, RESexamPrep.sg offers free practice without signup, SGExamReady has a seven-day trial, and RES Exam SG gives access to its first 50 questions.

ConfirmPass has two different free entry points: a five-question no-account preview and a free 20-question diagnostic.

Case-study numbers need context

Case-study numbers are particularly easy to compare badly.

RESPaper.sg publishes 194 case studies.

RESMockExams describes 8 case studies containing 80 Section B questions.

RESPrep describes its Hard Mode as 728 long case-study and multi-statement questions.

Those figures are measuring different things. One provider is counting case studies, another individual Section B questions, and another a broader group of longer scenario-style questions.

If case-study practice matters to you, look at the actual format rather than the biggest number.

What does “verified answers” really mean?

This is one area where a simple yes/no table would be misleading.

A provider can say that its content is reviewed, that its questions are mapped to the RES syllabus, that its team updates content when rules change, that official sources are referenced, or that its answers have been independently checked. Those are different claims.

RESMockExams says its content is reviewed and updated to remain aligned with CEA's published RES syllabus and examination focus areas.

RESExam.sg says its questions are based on the CEA syllabus and updated by its practitioner team as regulations change.

OpenExamPrep describes its questions as original practice questions modelled on the relevant syllabus.

ConfirmPass currently makes the narrower claim that its questions are mapped to RES syllabus topics and that reported errors are corrected through versioned rewrites.

We have therefore not used a simple “verified answers: yes/no” label. We also did not establish a public answer-level official-source citation system across the products reviewed. That is different from saying providers do not use official sources internally.

Notable differences between the paid options

ConfirmPass currently has 2,694 questions, fixed-duration passes with no auto-renewal, and a free diagnostic that combines correctness with confidence to identify weak topics and confident mistakes.

RESPrep combines topic questions, mock exams and Section B material, but its public pages currently contain conflicting question totals and conflicting billing language. If you are buying it, check the terms shown at checkout.

RESMockExams publishes the largest paid question-bank figure in this comparison at 4,300+ and also advertises dedicated Section B material.

SGExamReady is notable for one-time rather than recurring payment, while RES Exam SG is one of the clearer app-based paid options.

Propella remains in the table because the question-bank product is still publicly described, but we could not establish a reliable current price because its pricing page did not render a usable price when checked.

Which type of RES question bank might suit you?

There is no need to force every candidate into the same product.

If you want the largest clearly stated fully free bank, the Edmund Ee RES Revision Portal currently publishes 1,850+ MCQs, plus case studies and a mock exam.

If you want a large free case-study library, RESPaper.sg publishes 194 case studies alongside more than 1,100 free questions.

If you want the largest published paid question pool, RESMockExams states 4,300+ questions.

If you want to know where you are weak before paying for a question bank, ConfirmPass's free 20-question diagnostic is designed for that. It combines whether you were right or wrong with how confident you were, then breaks the result down by syllabus topic.

If you want both papers on a fixed pass rather than a recurring subscription, ConfirmPass uses fixed-duration access with no auto-renewal. SGExamReady also advertises one-time payment rather than a subscription.

If you want to practise mainly on your phone, RES Exam SG and NAVIS are app-based options.

If explanations matter most to you, try the free questions before paying wherever possible. “Detailed explanations” tells you less than seeing an actual explanation and deciding whether it helps you understand why an option is right or wrong.

Try the questions before choosing

A comparison can tell you what each provider publishes about its price, bank size and features.

It cannot tell you whether you like the questions.

If you want to inspect ConfirmPass's question style and worked explanations before deciding whether to use the full bank, try 20 free RES practice questions with answers and explanations.

A comparison cannot tell you what you personally need to revise

The other question is not which bank has the longest feature list.

It is which parts of the RES syllabus are costing you marks.

The free ConfirmPass diagnostic uses 20 questions and records your confidence alongside each answer. Your result then shows your topic-level performance and revision priorities.

Example ConfirmPass diagnostic result: confidence is compared with actual performance, then weak topics and confident mistakes are surfaced for revision.

That serves a different purpose from this comparison.

The comparison helps you decide which question bank you might want to use.

The diagnostic helps you decide what to work on next.
