As a lecturer, I'm always trying to find ways to make studies easier and more effective for my students.
One of my pieces of advice is to keep a 'blacklist' as you study.
As you study and do questions, note down the topics, details, areas that you're struggling with. Keeping them all in one place allows you to keep the 'stuff' you have to work on together. Gives you a 'birds-eye' view of what you need to work on before the finals.
Go through your blacklist every second day. Pick one item, and work on it for a bit. Once you've improved on it... cross it off your list. (That's always a great feeling!)
