any tricks on minimising the amount i have to learn
Learn one Q from B/C/D from Q6 very well, for example, learn everything about the wars etc and you can leave out social change and Irish history or vice versa.
Play to your strengths
Yes, rush over it but don't spend too much time on it. Spend time on the things you enjoy. The short questions are v easy and require pretty much to listen in class and you'll be sorted!
