Three months is enough to move your score a lot — if you spend it on the right things. The students who waste it are the ones who try to "finish the syllabus" again instead of fixing what actually loses marks.
The month-by-month shape

Month 1 fix gaps, month 2 high-weight mastery, month 3 mocks and revision.
- Month 1: diagnose and fix your weakest high-weight topics.
- Month 2: lock in the chapters that carry the most marks across all three subjects.
- Month 3: full mocks every few days, with deep analysis and revision.
A sustainable weekly split

Balance all three subjects every week — your weakest one drags your rank most.
Give every subject weekly attention — neglecting your weakest one is the most common 3-month mistake. Balance beats bingeing one subject for a fortnight.
Build the mock habit early

Ramp mocks from occasional to frequent so you peak at exam time.
Your score in three months is decided by the marks you stop losing, not the new chapters you add.
Start week one by being precise about where you stand. A quick Dakhilaa diagnostic names your weak high-weight topics, so your whole three months points exactly where the marks are.
