I enjoy the harder stuff in 4U but not too hard. If it's easy and over quickly I also enjoy it.
This basically means that
1. I hate graphs. They take forever and yet are ridiculously easy.
2. I hate a whole bunch of the probability ones. The fact that there are so many ways of approaching it means that I will try to do more than one in my head and I usually don't know how to progress.
As for everything else, I usually really enjoy it.
1. Complex number questions are quick and painless and often border on fairly stimulating
2. Conics are pretty decent, I just have difficulty in understanding what they're after sometimes (this is what I've been working on the most lately
)
3. Integration is good. First question done in 7 minutes. However when the I(n) questions are in the last question, I sometimes struggle a bit.
4. Polynomials are pretty good. It quickly gets to the stage where once you've answered one question, you've answered them all and yet they're fast enough to solve.
5. Volumes is just another form of integration really. All good.
6. Circle geo used to be really bad just because of the vast variety of possible rules. I've improved a lot now and they're worked out in a few seconds and written out in less than a minute most of the time (given that they never ask for any more than 2 (maybe 3) marks worth before asking another question related)
7. Mechanics are so good. I love the way the numbers move around and slot in...
8. The inequalities for harder 3 unit is pretty good.
9. Induction is too easy. They always give away too many marks :/
