"I forget the formulas": how to make them stay
You revised the formulas last night, and by the third question they are gone. Formulas that are only memorised fade fast. Formulas that you understand come back.
Why it happens
The usual causes
No meaning attached
A formula you cannot derive is a random string.
Memorising in one go
One night of cramming gives short-term memory only.
No active recall
Reading the formula list feels like knowing, but recall is what counts.
Too many formulas at once
Fifty formulas in one sitting overload memory.
What usually makes it worse
- Memorising by rereading
- Learning all formulas the night before
- Copying a formula list without using it
What helps
Five steps to start this week
- 01Derive or draw it
Show where area of a triangle or the quadratic formula comes from. A formula you can rebuild is yours.
- 02Make a one-page sheet per chapter
Writing it is half the learning.
- 03Quiz yourself
Cover the sheet and write each formula from memory. Mark what you missed.
- 04Space it out
Recall after one day, three days and a week.
- 05Use them in questions
A formula used in ten questions will stick more than ten reads.
If you wait
The cost of leaving it
Last-minute cramming raises anxiety and fades quickly, while spaced recall builds memory that survives the exam hall.

When to ask for help
A teacher can show where each formula comes from and set up a short recall routine with you.
FAQ
Questions people ask
Is it okay to memorise formulas?
Yes, after you understand them. Understanding makes memorising easier and lasts longer.
How many formulas should I learn a day?
A handful, with recall of earlier ones. Slow and steady works.
What if I forget a formula in the exam?
Try deriving it from a simple case, for example check with small numbers.
