How Long Should You Study for the RES Exam?

There is no single "X hours" answer to how long it takes to study for the RES exam — and anyone who quotes you a fixed number is guessing. What actually decides your timeline is simple maths: how many hours you can put in each week, and how much of that time is spent practising rather than passively reading. The smart move is to work backwards from your sitting date and protect a realistic number of consistent weeks. This guide shows you how.

Start from the exam, not the calendar

Before you plan a single study session, get the format straight so you know exactly what you are preparing for:

Two papers, each needing 60%, means you are effectively studying for two exams — budget time for both. For the full strategy that ties this together, read how to pass the RES exam.

Work backwards from your sitting date

Singapore's RES sittings are spaced roughly four months apart. In 2026 they fall on 14–15 March, 18–19 July and 31 October–1 November. Because the gaps are so wide, missing a sitting because you ran out of prep time can cost you months — so pick your date first, then count the weeks back and be honest about the hours you can commit.

Register early so you lock in your slot. Our RES exam registration guide walks through the steps and deadlines.

How weekly hours change your timeline

As a rough planning benchmark, most candidates want somewhere in the region of 60 to 80 hours of focused study across both papers. That is not an official figure — it is a working estimate — but it makes the arithmetic clear. The same total looks very different depending on how many hours you can spare each week:

Notice the pattern: doubling your weekly hours roughly halves the calendar. But there is a floor — cramming 60+ hours into a single week does not work, because you need repeated exposure over time for the material to stick. This is why someone doing a steady 10 hours a week often outperforms someone who binges 25 hours the week before and nothing before that.

Consistency beats total weeks

The candidates who pass first time are rarely the ones who studied the longest — they are the ones who studied regularly. Three short sessions a week for two months will beat one exhausting marathon day, because spacing and repetition are what move knowledge into long-term memory.

• Your background. A legal, finance or property background means some topics already feel familiar — you may sit at the faster end of the table above.
• Your consistency. Regular short sessions compound; sporadic all-nighters do not.
• Your practice volume. The single biggest lever. See below.

Practice volume matters more than reading time

The most common — and least effective — way to spend your hours is reading notes cover to cover. Retention comes from active recall: testing yourself, then reviewing every wrong answer until you understand why the right answer is right. Read a topic once, then immediately practise questions on it. A split that works well is roughly 30% reading, 70% practising.

Section B case studies deserve dedicated drilling — they reward applying rules to a scenario rather than recalling a definition, and they are where many candidates quietly lose marks. More tactics in our RES exam tips.

How to know you are actually ready

Forget the calendar — the real signal is your scores. When you are reliably clearing 60%+ on full timed mock papers for both papers — not by luck, but consistently — you are ready. If you are not there yet, give it another week rather than gambling on the exam fee and a four-month wait for the next sitting.

Test where you stand right now with a free timed mock (no sign-up needed), and keep the one-page RES cheat sheet handy so the numbers-heavy topics stay automatic.

Bottom line: your study timeline is a function of your weekly hours, not a fixed countdown. Pick your sitting date, commit to a consistent weekly pace, and spend most of that time practising. Create a free account and start today — the first 15 questions in every topic are free.
