How to study for CFA Level I: a plan that follows the exam's weights
Most people who fail Level I do not fail from lack of effort. They spend their hours in the wrong proportions, read without practising, or learn something and then do not see it again until it has faded. This guide describes a way of studying that works against all three. Nothing in it needs special tools, though the free ones linked here make parts of it easier.
Know what the exam is
Level I is a single exam of standalone multiple-choice questions, 180 of them in 4 hours 30 minutes, which works out at 1.5 minutes a question. Each question has a short stem and three options. It tests breadth: every topic in the curriculum is examined, and no topic is skipped. The Level I syllabus lists every topic and learning outcome, with each topic's weight in the exam. If you began on 2026 material, see what changes in the 2027 curriculum.
Two consequences shape everything else:
- Breadth beats depth. A candidate who knows 80% of every topic does better than one who knows everything about half of them.
- Speed matters. At 1.5 minutes a question there is no time to work out a method from scratch. The routine has to be automatic.
Start by finding out where you stand
Before you read anything, test yourself. A short quiz on every topic shows what you already know, which is usually more than you expect in some places and less in others. The free diagnostic test takes a few minutes, scores itself and breaks the result down by topic. Do not read much into the total: twelve questions is a small sample, and the page says so. Use the topic breakdown to decide where to begin.
Spend hours in proportion to weight, then adjust
Each topic carries a published weight in the exam. A topic worth 20% deserves roughly twice the hours of one worth 10%, other things equal. Other things are not equal: you should add time where you are weak and take it from where you are strong. The study-plan calculator does that arithmetic from your exam date, your weekly hours and how confident you are in each topic, and keeps a share of the time back for mocks and final review. For how to split a fixed number of weekly hours, see splitting your CFA study hours.
CFA Institute's own guidance is that candidates plan on a substantial number of study hours for each level. Whatever total you settle on, spread it over enough weeks that you can keep it up, because steady weeks beat a final sprint.
Learn it, then practise it straight away
Reading a chapter feels like progress and is the weakest form of study. The strongest is retrieval: trying to answer a question, getting it wrong and finding out why.
- Read or watch the material for one learning outcome, then answer questions on it the same day.
- Read the explanation for every wrong option, not just the right one. Distractors are written to match the mistakes people make, so knowing why each is wrong is half the learning.
- Keep a short list of the mistakes you make. They repeat.
- Do the calculations yourself on your calculator, so the keystrokes are automatic. The finance calculators let you check an answer when you are stuck.
Review before you forget
A topic learned in week two is half gone by week ten unless you meet it again. Spaced review brings each idea back just before it would be forgotten, with longer gaps each time it is remembered. The post on spaced review explains how it works and why it beats rereading.
Use mock exams as a range
Full-length mocks are the best preparation for the pace and stamina of the real thing, but a score on one is less precise than it looks. A mock is a sample of what you know. Two mocks of the same quality can differ by several points just by chance, which is why a single jump or dip means little. The post on reading a mock score shows how wide the range is, and the mock readiness checker turns your scores into a range and a trend.
A good pattern is to sit a mock about a month in to learn the pace, then several in the final weeks, and spend the time between reviewing what each one showed.
The last few weeks
- Stop learning new material a short time before the exam, and consolidate what you have.
- Fix the weak topics first, using your mock results and your mistake list.
- Rehearse exam day: timing, calculator, breaks, the route to the venue.
- Sleep. It beats one more late night of cramming.
Common mistakes
- Reading without practising.
- Studying favourite topics and avoiding the weak ones.
- Ignoring ethics. It is weighted heavily and is some of the easiest marks if you prepare.
- Skipping the calculator until the last month.
- Treating one mock as a verdict.
