Brevet Revision Schedule: How Much Time per Subject, per Week

# Brevet Revision Schedule: How Much Time per Subject, per Week

An effective brevet revision schedule allocates your time according to two things: how much each exam weighs in the final grade, and the gap between your current level and the expected level, then spreads sessions across the week instead of cramming everything the night before. You are in your final year of middle school, the brevet is approaching, and you are wondering how many hours to spend on each subject. The real question is not "how much time total" but "how much time on what, and when". That is exactly what we will build here, slot by slot.

TL;DR: A good brevet schedule starts with a diagnostic (where your gaps are), then prioritizes each subject by its weight and your level. You then spread short 30 to 45-minute blocks across the whole week, alternating subjects, with a daily quiz block to test yourself. The key rule: four one-hour sessions spread across the week beat a single four-hour session on Sunday night. The schedule does two things, it guarantees spacing and it cuts stress by removing uncertainty.

What is the brevet? The brevet (diplôme national du brevet, or DNB) is the French national exam taken at the end of middle school, around age 15. It combines continuous assessment from the school year with end-of-year written exams in French, mathematics, science (a mix of biology, physics-chemistry, and technology), and history-geography-civics. The planning method below is fully transferable to any end-of-school exam that mixes several subjects with different weights.

Cognitive science research is clear on one point that changes everything. Cepeda, Pashler, Vul, Wixted, and Rohrer (2006) showed that spreading your revision over several days (distributed practice) produces significantly higher retention than massed cramming. Working on a subject for five hours straight is less effective than five one-hour sessions spread across the week. Your schedule is not an organizational chore: it is the tool that forces you to space out, and therefore to retain better.

This article gives you a concrete method. First how to decide the time per subject, then a complete sample week from Monday to Sunday, and finally how to fill your slots with work that actually pays off.

Why build a schedule instead of revising on the fly?

Revising "when you feel like it" always produces the same result: you do the subjects you enjoy and avoid the ones that scare you. But those are often the ones that weigh most in your grade. Without a schedule, your time goes where it is comfortable, not where it counts.

A schedule solves two problems at once. The first is spacing. By deciding in advance that a given subject comes back on Tuesday, Thursday, and Saturday, you guarantee you will not see it once then never again. Pashler, Rohrer, Cepeda, and Carpenter (2007) showed that optimal spacing depends on the time before the exam: the further away the exam, the more you can space out. If the brevet is six weeks away, reviewing each concept every 4 to 7 days is a good rhythm.

The second problem is stress. Anxiety mostly comes from uncertainty: "will I make it, am I doing enough". When every evening you know exactly what you did and what you will do tomorrow, that uncertainty disappears. The schedule turns a vague mountain into a list of checkable blocks. It is reassuring because it is concrete.

The brevet: what actually counts in the grade?

Before allocating your time, you need to know where the points go. The brevet combines continuous assessment from the year with end-of-year written exams. The written exams cover French, mathematics, science (a mix of biology, physics-chemistry, technology), and history-geography-civics.

Not every exam calls for the same kind of work. French and history-geography reward comprehension, writing, and memorizing reference points. Math rewards practicing standard exercise types. Science mixes facts to memorize with reasoning over documents. Your schedule should reflect these differences, not mechanically give everyone the same time.

The idea is not to revise everything equally. It is to cross two questions for each subject: how much it weighs, and how comfortable you are with it. A heavy subject you struggle with deserves a lot of time. A subject you are already solid in deserves only upkeep.

How do you decide how much time to give each subject?

Start with an honest diagnostic. Take a mock brevet paper in each written subject and do it without your notes, timed. Record your results chapter by chapter, not just the overall grade. A 10/20 in math might hide a 15 in geometry and a 5 in functions. That precision is what guides everything else.

Then rank each subject in a priority grid. You cross the exam weight (high or medium) with your current level (gaps or solid). Here is how to read your grid.

The zone to attack first is obvious: high weight and major gaps. That is where every hour yields the most points. Subjects where you are already comfortable go into upkeep mode, one session per week is enough to hold your level.

From this grid, you can set time benchmarks. Here is a sample weekly allocation for someone with 8 to 10 hours of revision per week on top of classes. Adjust based on your diagnostic.

These figures are a starting point, not a law. If your diagnostic shows math is your weak spot and it weighs heavily, bump it to 3 hours and lower a subject where you are solid. The principle stays: time follows weight and gaps.

What does a sample brevet revision week look like?

Now that we have the time benchmarks, here is how to fit them into a real week. The guiding principle is alternation: you do not do a full day of math then a full day of French. You alternate subjects from one block to the next. This alternation, interleaving, improves your ability to tell problem types apart and mobilize the right method at the right time (Rohrer & Taylor, 2007), even if in the moment it feels harder.

Each block lasts 30 to 45 minutes, followed by a 5 to 10-minute break. You do not exceed 3 to 4 blocks on a weekday, because beyond that your attention drops and the extra time barely pays off.

A few principles to bring this table to life. Saturday is reserved for a complete mock exam in one subject, under real conditions, followed by self-correction. You rotate the subject each week to cover all the exams over the month. Sunday stays light: a subject where you are already solid, then real rest. The brain consolidates during breaks, not only during work.

The daily quiz block is the heart of the system. It is what ensures active recall and spacing. A few minutes each day testing yourself on weak concepts is far better than one big re-reading session once a week.

How do you fill your slots with work that pays off?

Having a schedule is not enough if you fill your blocks with passive re-reading. Re-reading gives a false sense of mastery: you recognize the material, so you think you know it, when recognizing is not recalling. Roediger and Karpicke (2006) showed that testing yourself on content produces roughly 50% more retention than re-reading it. Every block should therefore contain a share of active recall.

The method for an effective study block has three steps. First you read the chapter once, actively, turning each part into a question in the margin. Then you close the material and write on a blank sheet everything you remember. Finally you compare: the gaps are your priority targets. This is active recall in action, the highest-yield lever of all revision methods (Dunlosky, Rawson, Marsh, Nathan & Willingham, 2013).

For the daily quiz block, this is where a tool like Wizidoo saves time. You take a photo of a page of your notes or import the PDF, and the AI generates quizzes tailored to your chapter. Instead of building your own questions, you directly fill the active recall slot in your schedule. Important: the app does not decide your schedule. You build the schedule yourself, based on your priority grid. Wizidoo provides the recall tool that fills the slots you have decided on.

One detail that changes everything for spacing: in Wizidoo, the concepts you have not yet mastered (not two correct answers in a row) automatically come back in your next quizzes, in successive layers, from fundamentals to details. You do not need to track which concept to review: your daily quiz block surfaces what is not solid on its own. The spacing effect emerges from this mechanic over your sessions.

Finally, use the diagnostic continuously, not just at the start. The mastery percentage per subject and per chapter tells you where you are progressing and where you are stalling. That is what lets you adjust your schedule each week: if a subject stays red, give it an extra block the following week. The schedule is not fixed, it corrects itself with the data.

The right mindset to stick to your schedule

A perfect schedule you do not follow is worthless. Better a slightly less ambitious schedule you actually keep. If you planned 4 blocks and only do 3, that is not a failure, it is 3 blocks gained. Consistency beats intensity.

Do not compare yourself to a friend who started three months ago. Compare yourself to yourself last week. Every chapter turned green, every corrected mock exam, every successful quiz is one concrete point more on exam day. That is what the schedule makes visible: not a mountain, but progress.

And keep sleep among your priorities, even in full revision mode. A concept seen at 11 pm by sacrificing an hour of sleep is retained worse than a concept seen at 6 pm in your planned block. Sleep consolidates what you learned during the day. Protecting your nights is part of the schedule, not the opposite.

Frequently asked questions

How many hours per week does revising for the brevet take?

There is no magic number, but 8 to 10 hours spread across the week on top of classes is a realistic benchmark one or two months before the brevet. What matters is not the raw total but the distribution: short sessions spread over several days beat one big weekend block (Cepeda et al., 2006). If you have less time, prioritize the daily quiz block and the high-weight subjects where you have gaps. For a complete method, see our guide on revising for the brevet effectively.

Should you revise every subject every day?

No. Revising everything every day dilutes your attention and prevents deep work. A 3 to 4-day rotation is more effective: each subject comes back 2 to 3 times per week, which is enough to maintain good spacing. Priority subjects (high weight and gaps) come up more often in your week, subjects where you are solid go into maintenance with a weekly quiz. Only the daily quiz block is present every day, because it cycles through all the weak concepts.

How do you know which subject to prioritize?

Cross two things: the exam weight and your real level measured by a mock exam. Maximum priority goes to high-weight subjects where you have major gaps, because that is where every hour yields the most points. The mastery percentage per chapter, like the one Wizidoo displays, gives you an objective measure to decide, instead of relying on your impression, which is often misleading. You then adjust your schedule each week based on what remains fragile.

Does cramming the night before the brevet work?

No, and it is actually counterproductive. Cramming heavily the night before creates interference and tires your brain at exactly the wrong moment. The night before, do a short quiz session on your most fragile points, re-read your method sheets, then stop. Go to bed early: the previous night's sleep consolidates what you know and keeps you sharp. If you are really behind, see our last-minute 2-week revision plan instead.

How do you handle history-geography, which needs a lot of memorization?

History-geography rewards memorizing reference points (dates, places, concepts) and connecting them. That is exactly the territory of active recall and spacing: turn your reference points into questions, test yourself on them regularly, and bring the fragile ones back in your daily quiz block. Maps are worked by redrawing them from memory, not by looking at them. For a dedicated plan, see revising brevet history-geography in 30 days.
