Studying for an Exam While Working Full Time: A Plan

Studying for an exam while working full time works when you plan backward from hours. Take the hours your exam's own body reports, divide them by the hours you can protect each week, and you have the length of your prep. At 12 hours a week, a 300-hour CFA level takes about 25 weeks; a 100-hour GMAT prep, about 9.

How many hours your exam takes

Start with the number the exam's owner publishes, not a prep company's. Here is what each says, and what the number means:

Two cautions apply. The CFA and GMAT figures come from people who did well, so they describe success, not the minimum. People who studied less and passed are in the average too, and so are people who studied more. And all three are averages: your background moves them. GMAC adds a calendar view, calling two to three months of focused prep "usually ideal", and defines its top scorers as those at the 89th percentile or above.

For the MCAT, the AAMC's own survey data and the hours a day it implies are in how many hours a day to study for the MCAT.

If you're working out how to study for CPA while working full time, plan section by section. The AICPA describes a four-section, 16-hour exam: three four-hour Core sections plus one four-hour Discipline section you choose. Split evenly, 350 to 450 hours come to about 88 to 113 a section. The sections aren't equally hard for everyone, so treat that as a first split and adjust after the first one.

Studying for an exam while working full time: hours into weeks

Divide the exam's hours by your weekly hours. The table does the arithmetic, rounded up to whole weeks:

GMAC's "two to three months" matches the 12-hour column: 100 hours at 12 a week is about two months. Read your row, then check it against your calendar. If 38 weeks don't fit before the exam date you wanted, you need more hours a week, a later date or both. If you're studying while working full time, count the weeks that will disappear: holidays, sick days and a crunch at work. Plan for the slower column, and treat a faster pace as a bonus.

Where the hours come from on a workday

The time has to come from somewhere, and federal data shows where it is. In the American Time Use Survey, full-time workers' days on the job break down like this:

Educational activities, inside "everything else", took 0.06 hours: about four minutes. Leisure took nearly three hours. A plan around a job mostly trades some of that leisure, not sleep, which is why the plan below keeps weekday sessions short.

The same survey's 2025 release found that 81% of employed people worked on an average weekday and 30% on an average weekend day. For most, weekends are where the long blocks fit.

Split the week between weekdays and weekends

Weekday evenings suit short, repeatable work: practice questions, flashcards and review. Weekends take the long jobs: new topics, full problem sets and timed mock exams. Three splits that add up:

The 15-hour plan leaves no day off, so keep it for the last two months, not the whole prep. What to do on an evening when you're spent is in how to study after work when you're tired.

Fix the start times, not just the totals: a slot that's already decided doesn't have to be found each day. On StudyDuo, Study Hour is the same hour every day for everyone, shown in your time zone. A 1:1 session lets you post a time for a partner to join you on video.

Plan the phases, not just the hours

GMAC describes GMAT prep in three stages, "learning concepts, practicing under time pressure, then undertaking full mocks", in that order. The same order works for most long exams, and when you're studying for an exam while working full time, it tells you what each part of the week is for:

For the mocks, GMAC's advice is to "practice taking the test under the same conditions you will be taking it on test day", start time included. It also warns against stopping and starting: "Try not to lose momentum and stop and start your studies". Four short evenings a week follow that better than a plan that saves everything for Saturday.

Ask for study time at work

Some employers give study or exam leave; ask HR before you build the plan, because a few paid days before the exam change the last month. In the UK, the law gives some employees a right to request time off for training. You must be an employee with at least 26 weeks' service, at an organization with at least 250 people, and the training must help you do your job better. The time off is "usually unpaid unless the employer agrees to pay it."

Also check your work calendar. If your job has a busy season, put the exam outside it, and plan your heaviest study weeks around it too.

When to move the exam date

A plan rarely holds week by week, so judge it by the monthly total. Run a check six weeks out: multiply the weeks left by your real weekly hours from the last month, and compare that with the hours still missing. If you're short by more than two weeks of study, decide now, while moving the date still costs little.

Rules differ by exam, and some are strict. The CFA Institute's deferral policy lets 2026 candidates buy a USD 449 deferral of up to 12 months. For 2027 exams, the same page says "paid deferrals will no longer be offered". That leaves emergency deferrals for listed reasons, such as a life-threatening illness, with a USD 100 processing fee. For 2027, pick a window you can make. Whatever your exam, read its cutoff and fee for moving the date when you book, not when you're behind.

Count hours, not good intentions

Log every session's real minutes, and total them each Sunday against the plan. Hours are the unit your exam body used, so they're the honest measure of progress. Over months of studying for an exam while working full time, that weekly total is what tells you whether the date still holds. On StudyDuo, the minutes you spend in the rooms add up to hours, and 30 minutes a day keeps a streak going. If you fall short two weeks running, recalculate the weeks left from your real pace instead of promising bigger weeks later. If a friend is studying for something too, comparing weekly totals adds a little pressure; study trackers you share with friends are compared in their own guide.
