Depending on the learning aspect it may be better to study on the key points. Make small reminders or ways to remember them. ( Ex. Navigational points - North East South West, clockwise. Ned Eats So much Weed. Kid friendly, Ned Eats So many Watermelons )
As well as the topics in the beginning of the year may be useful to have as they contain the foundation of information needed. If you need to, create a few notes about each topic and go through them, so it'll be easier to remember when you take your test.
