Break the section down into bits (use the revision guides for guidance) e.g enzymes, cell structure, fractions etc
With each section, write down all the information you dont know/cant always remember on a piece of paper
Then try and write down as much as you can from memory straight afterwards, an hour afterwards and a day afterwards.
The stuff youve written by remembering is the stuff you can cross off the original sheet.
Keep repeating this until you can cross of more and more of the information on the original sheet because its in your memory.
Thats the main technique i used for as levels when i realised i didnt know anything and i got a B in the subject i knew nothing about in under a week 😂
Apart from that:
Dont make mindmaps pretty, make them and then chuck them and make them again.
Always revisit topics even if you have studied it and remembered the information previously - aim to recap each section every 2 weeks.
Do practice exam papers, these are so valuable
For stuff like English and history, read examiners reports to understand how to answer each question
In general, dont worry. I though gcses were the most important things in the world, but as long as you get a pass in english and maths, you have the world at your feet. Even if you dont, you get chances to retake and some HE courses let you on anyway
