^ basically what Nailgun said.
This was me this year. Year 11 teacher was an absolute legend but he moved ;n; Now literally just grasping for any other sources I can find. It helps to talk to past students and get them to clarify anything you don't understand if your teacher is that bad.

Rather than Perms and Combs which many seem to find the hardest, I would probably say either Motion or Binomial - both of which have pretty easy concepts to grasp but the wording of questions can kinda get a bit confusing.
When you integrate -1/3 . e^-x/3 you get e^-x/3, as shown by the rule photastic stated. This is then multiplied by the -3 that was pulled out at the start to get the -1/3 inside the integral so you get a final answer of -3e^x/3
That's pretty much what I do. I still write a general essay beforehand but yeah idk how people memorise their essays o_o That's crazy how do they remember all that eughh
