i pretty much promised myself to get most of unit 3 done over the holidays for all my subjects but now i'm thinking that it was a bit ambitious.. so yeah i definitely need to remember to relax and try to have at least a little fun, thanks for the advice
Yeah, that's not a good idea! You'll probably find yourself skimming through content and not have a true understanding either. Remember, if lots of people are struggling to cope with the workload when given 6 months (roughly), it's certainly not going to be easy to finish half a years content in this time, not to mention you don't have a teacher to help you out either.
Also, lots of people tend to slack off in class because they've heard half the stuff the teachers saying (read:half) so they end up missing the other half which they might have skimmed over. Of course, everybody's different so maybe you might absorb everything, but I'm generalising

I do know some people who do work far ahead for some subjects that they find very easy, a lot people choose to cover a lot of further maths course work.
