So trials are around the corner and I'm starting to worry about my study technique. For all of my subjects, I have been writing notes throughout the year, however, they are messy and have gaps in them. In the past, I have never even bothered reading my notes and just jump into doing as many past questions as possible and using the textbook if I have any problems. This has worked for most of my subjects (Ext math, physics, Visual Art). However, my main concern is economics, my economics notes are extremely weak with many topics not even touched. I have been doing past papers and only been averaging 60%, should I attempt to rewrite a whole set of notes or continue to pump out past papers?
