Pin down exactly what you are entered for

4 this week

Ask your exams officer for your statement of entry and check the syllabus code and entry option code for every subject, since 0580 and 0980 and 0607 are different qualifications.
Confirm your tier in every tiered subject. Core entry in Mathematics 0580 caps you at grade C; Extended entry opens A* but examines Supplement content you may not have been taught.
Find your administrative zone, because zone determines which paper variant you sit and therefore which past papers match your exam.
Download the correct syllabus year from cambridgeinternational.org for each subject, not last year's version.
Write out the paper structure for every subject on one page: paper number, duration, marks and percentage weighting.

Build the topic checklist from the syllabus, not the textbook

5 this week

Copy the subject content headings from each syllabus into a checklist and rate yourself red, amber or green on each line.
In Extended science and maths subjects, mark which lines are Supplement content, since those carry the grades above C.
Read the command words section at the back of each syllabus and write your own one-line definition of state, describe, explain, calculate, suggest and evaluate.
Read the assessment objective weights: Biology 0610 is 50 per cent AO1, 30 per cent AO2 and 20 per cent AO3, so a fifth of the grade is experimental skill.
Count how many red lines you have per subject and use that number to allocate revision time, not how much you enjoy the subject.

First timed paper in your two weakest subjects

6 this week

Sit one full past paper under exam timing in each of your two weakest subjects, using the variant that matches your administrative zone.
Mark it yourself against the published mark scheme, awarding marks only where your wording matches the accepted answers.
Read the examiner report for that paper and list every error the report says candidates commonly made that you also made.
Look up the grade threshold table for that series and convert your raw mark into a grade so you know where you actually stand.
Record your mark per question, not per paper, so you can see which topics are bleeding marks.

Command word discipline

5 this week

Take 20 past paper questions across subjects and answer only the command word, writing nothing extra.
Practise the difference between describe and explain in the sciences: describe reports what happens, explain gives the mechanism or the reason.
In Mathematics 0580, practise writing full method lines, because method marks are available even where the final answer is wrong.
In History 0470, practise the source questions separately from the essay questions, since they use different mark schemes.
Rewrite five of your weakest answers from the week 3 paper to full marks using the mark scheme wording.

Practical and alternative to practical skills

6 this week

Confirm whether you are entered for Paper 5 Practical Test or Paper 6 Alternative to Practical in each science, because they need different preparation and both are worth 20 per cent.
For Paper 6, drill the recurring tasks: reading a measuring cylinder or thermometer, tabulating results with correct units and significant figures, plotting a graph and drawing a line of best fit.
Practise identifying the independent variable, the dependent variable and the variables to control in five unfamiliar experiments.
Practise writing improvements and sources of error in the specific wording examiners accept, taken from mark schemes.
For Paper 5, rehearse the apparatus listed in the syllabus so no piece of equipment is new on the day.

Non-calculator arithmetic and the calculator papers

6 this week

Mathematics 0580 Paper 1 at Core and Paper 2 at Extended are non-calculator papers, so drill fractions, surds, standard form and long multiplication by hand.
Work 30 questions per session against a clock, since Extended Paper 2 gives 2 hours for 100 marks, roughly 1.2 minutes per mark.
On the calculator papers, practise entering multi-step expressions in one go rather than rounding at each stage.
Learn which formulas are given on the Core list and which on the Extended list, and memorise the ones that are not.
In the sciences, practise unit conversion and significant figures, which examiner reports repeatedly flag as avoidable losses.

Extended writing subjects

6 this week

In Literature in English 0475, write one timed essay per set text and check it against the assessment criteria for the paper.
In First Language English 0500, practise the directed writing task to the exact word count, since going long costs time not marks.
In History 0470, build a one-page timeline per depth study and write three timed source-based answers.
Practise planning for 4 minutes before writing on every extended response, and keep the plan on the paper.
Ask a teacher to mark one essay per subject against the published criteria rather than giving general comments.

Second full mock across all subjects

10 this week

Sit a complete past paper in every subject across the week, in the correct order and to the correct timings.
Use the same variant series for all subjects so the threshold tables give you a coherent grade profile.
Convert every raw mark to a grade using that series' threshold table and to a percentage uniform mark band using the 20 to 100 scale.
Identify the two subjects sitting closest to a grade boundary, because a few marks there move a grade.
Rebuild your red-amber-green checklist from week 2 with the mock evidence rather than your impressions.

Attack the boundary subjects

8 this week

Take the two subjects nearest a grade boundary and do three more past papers each, spaced across the week.
For every mark lost, write the syllabus line it came from and revise that line specifically.
Redo, from memory, the questions you got wrong in the mock rather than reading the answers.
Check whether a tier change is still possible with your exams officer if a Core entry is clearly capping you below your ability, since entry deadlines close months before the exams.
Drill the highest-frequency topics from the examiner reports for those two subjects.

Full syllabus sweep against the checklist

9 this week

Work through every remaining red line on every subject checklist, one subject per day.
Convert each red line into three practice questions pulled from the past paper archive rather than reading notes about it.
Build a single page of formulas, definitions and required practicals per subject.
Test yourself on those pages from blank paper twice, on different days.
Stop making new notes after this week and switch entirely to questions.

Third mock and pacing under real timing

9 this week

Sit one more full paper per subject, this time recording the clock time at which you finished each section.
In Biology 0610 Extended, check you completed the 40 multiple-choice items of Paper 2 inside 45 minutes, which is 67 seconds per item.
In Mathematics 0580 Extended, check you had reached 50 of 100 marks by the 60-minute point of each 2-hour paper.
Leave nothing blank in any paper, since Cambridge does not deduct marks for wrong answers on these papers.
Note every question where you ran out of time rather than out of knowledge, and practise that question type specifically.

Logistics, equipment and taper

5 this week

Check your personal exam timetable against your administrative zone's timetable, including the date, start time and room for every paper.
Pack a clear pencil case with black pens, pencils, ruler, protractor, compasses and a scientific calculator with fresh batteries for the calculator papers only.
Confirm any access arrangement your school agreed with Cambridge is in place, since these have to be approved before the exams, not on the day.
Reread only your one-page summaries and your error logs, and stop full papers 48 hours before your first exam.
Sleep on a fixed schedule for the final week and plan travel so you arrive well before each start time.
