7 Study Mistakes That Make CFA Candidates Fail

Fewer than half of Level I candidates pass. In 2026 the pass rates were 45% in February, 39% in May and 43% in August, according to CFA Institute. Many of the people who fail put in the hours. What went wrong is usually how those hours were spent.

These are the seven habits that cost hard-working candidates the most, and what to do instead.

1. Giving every topic the same time

Level I has ten topics, and it is tempting to give each one a tenth of your time. But the weights are very different. Ethics is 15–20% of the exam. Derivatives is 5–8%. Spending 30 hours on each means giving equal time to a topic worth roughly a third as many questions.

The opposite habit is just as common: spending extra time on the topics you enjoy because progress there feels good, while the harder ones wait.

Instead: start from the topic weights, then adjust for your background. A sensible split of 300 hours gives ethics about 50, financial statement analysis and fixed income about 40 each, and derivatives about 20. Our study schedule guide has the full table.

2. Reading instead of practising

Reading and highlighting feel like work. You finish a chapter and it all seems familiar. The problem is that familiar is not the same as usable. The exam does not ask whether you recognise the dividend discount model. It gives you a dividend, a growth rate and a required return and asks for a value in about 90 seconds.

Instead: after each reading, close the book and do questions on it, the same day or the next. When you get one wrong, go back to the specific section, not the whole chapter. A useful check is to write a topic's key formulas on a blank page from memory. What you cannot write down, you do not yet know well enough for the exam.

3. Taking the first mock too late

Many candidates wait until they have "finished the curriculum" before trying a full mock. By then there are three or four weeks left. The mock shows exactly what is wrong and there is no time left to fix it.

Instead: take your first full mock six to eight weeks before the exam, even if you have not covered everything. A low first score is normal and useful. It tells you where to spend the remaining weeks. Our guide to CFA mock exams covers timing, how many to take and how to review them.

4. Leaving ethics until the end

Ethics looks like common sense, so it often gets a quick read in the final weeks. That is a mistake for two reasons. It is the heaviest topic on Level I. And CFA Institute applies an ethics adjustment: for candidates close to the passing line, ethics performance can move them above or below it.

Ethics questions also do not reward cramming. They test whether you can apply the Standards to situations you have not seen before, and that comes from many small repetitions.

Instead: study the Code and Standards in your first month, then do 15 to 20 ethics questions every week until the exam. Our guide to studying CFA ethics covers the traps that catch most candidates.

5. Avoiding your weak topics

Working on a topic you are bad at is unpleasant. Every session reminds you of what you do not know. So candidates drift back to topics where they already score well, and their weak topics stay weak.

The arithmetic points the other way. Moving a topic from 80% to 85% gains a few questions. Moving a topic of similar weight from 50% to 65% gains three times as many.

Instead: after each mock or large practice set, list your topics by score and weight. Spend most of your next week on the one that combines a low score with a high weight. Keep strong topics warm with a short mixed set every few days, but do not let them take your best hours.

6. Not reviewing mistakes properly

A mock exam takes four and a half hours. Many candidates then spend ten minutes on the result: look at the score, feel good or bad, start the next one. Most of the value of a mock is in the review, and skipping it means making the same mistakes again.

Instead: for every question you got wrong or guessed, write down why:

• Knowledge: you did not know the concept or formula.
• Reading: you knew it, but misread the question, a unit, or a "least likely".
• Time: you rushed because an earlier question took too long.

Each kind has a different fix. Knowledge gaps need study. Reading errors need a slower first read. Time problems need timed practice and a firm rule for when to move on. Keep these notes in one place and read them again before each mock.

7. Knowing the material but not the exam

Some candidates understand the curriculum well and still fail, because they have never practised under exam conditions. They spend four minutes on one calculation, run short of time in the second session, or lose focus in the final hour.

Level I gives you 1.5 minutes per question across two sessions of 2 hours 15 minutes. Working at that pace, for that long, is a skill of its own.

Instead:

• Time your practice sets at 1.5 minutes per question from the middle of your preparation onwards.
• Use only your approved calculator (the Texas Instruments BA II Plus or HP 12C families) for all practice, so its functions become automatic.
• Set a rule for stuck questions: no clear route after a minute, make your best guess, flag it and move on. There is no penalty for wrong answers, so never leave one blank.
• Take full mocks in one sitting, with only the break you will have on the day.

The common thread

None of these mistakes is about intelligence or effort. They are about getting feedback early and acting on it. Candidates who pass tend to find out where they lose points sooner, and then spend their time there rather than where it feels comfortable.
