On the inside cover, there are various post-it notes. The top one on the right shows the colour codes used for each topic so that I write my random notes in the right section and in the right colour.
Each page is dedicated to a specialty and the notes are derived from practice questions I've done or random things I've read online. Within each section, there are subheadings which are also written in the colour code seen above. I've divided a line down the middle of each page because I find the size a bit too large for me to write horizontally continuously an still keep things neat.
The Moleskine quality still isn't great and doesn't seem to have improved much and the only pens that seem to do well on it are biros, my Pilot Juice gel pens and pencil. However, they were the perfect size (and price) for what I needed at the time (not quite A4 but larger than A5) and the narrow rule is something I have an affinity for when it comes to paper.
