I am going to fail my mocksWatch
Different people learn differently, but biologically, combining various methods is your best bet. Some examples include:
-Repetition; repeating key information forms strong bonds in your brain and makes it easier to access and it eventually becomes a part of your long term memory. This is especially ideal for languages (e.g. Learning vocabulary)
-A strong stimulus; strong stimulus - including colour, light, smell or sound - helps us to remember things. A famous example of this is eating a certain flavour of Skittles while learning a key fact, then eating the same flavour right before an exam to help you recall the memory of learning it. This might be useful for maths or sciences
-Patterns; you're more likely to remember something if you can make a pattern out of it. Say you have a list of phrases you need to learn: try to get them into a little story or song that you'll remember.
As I said, it's different for everyone, but it's worth trying it out for yourself.
Hope I helped good luck!
