Tips for studying university modules

You really just need to break it down into small chunks and take it a part at a time. You might find it helpful to make mind maps or posters summarizing what you're trying to learn. Flashcards are okay, but being active with your revision (draw stuff, link things with arrows etc) is more likely to help than just reading notes and trying to memorise.

In the past I have also assigned silly quotes or one word reminders to my notes to help me remember a section (I write stuff in the margins during lectures to that effect too) and create associations between things. I had a module last year where I needed to learn a really complicated molecular pathway and I just could not make it stick, every time I thought I knew it I'd try to test myself and forget it all again; in the end, I came up with hand gestures for each step I think I looked silly in the exam, but it worked.

So yeah, you just have to come up with some techniques that work better for you if what you're currently doing isn't working.
