Questions

Which formulas are given in the GCSE maths exam?

It depends on the exam board and the year, so check the current formula sheet from your board. Learn the common ones anyway: it saves time in the exam.

How do I remember formulas?

Use them. Write a formula from memory, then use it in a question straight away. A short topic test every few days does more than reading a list.
