I suck at proofs and some of the harder complex number stuff and it wasnt that bad in the sample but some of the past papers i have done have so much of it

just basic knowledge like integration, projectile etc. but not topics like binomial distribution, perms and combs..

Oh yeah true. But like I'm not bad at any topic I just drop marks here and there for random questions and them it all adds up to like 70 percent
THIS IS ME LOLOh yeah true. But like I'm not bad at any topic I just drop marks here and there for random questions and them it all adds up to like 70 percent

The struggle is real. I'm just praying at this point that I don't make silly mistakes on Monday
Yes but not a big part of the exam. For example, pigeonhole principle as a sub question is very much possible (sample paper).

So anyone have predictions for the hardest couple of questions? Hopefully 11-14 are 'filler' types cause 15 + 16 are gonna hit hard haha
I'm predicting we'll have one of those miscellaneous induction ones where its straight logic

I'd love to have one of those. Honestly wouldn't mind any topics except for Vectors haha.

Does anyone think there will be a forced complex substitution for integration in 14 or 15? I think it would make an interesting question and might separate those who have studied more from those who haven't

Not sure how an integration question with a given substitution can really separate those studied vs those who haven’t?

Complex substitution man like being forced to solve integral of sin^5(x) via separating into terms of e^ipi. I’ve seen it maybe 3 or 4 times in trials and miscellaneous questions so it’s fairly rare.
If they "force" you to use a certain method they must provide enough details for you to discern what the method is, and then it becomes easier (e.g they cannot say using complex numbers integrate etc)

Unlikely going to happen because the syllabus only covers integration over real numbers. You start to run into rigour issues (e.g. how do you account for the fact that ordering does not exist for complex numbers like it does for real numbers?) that need to be established first when integrating over the complex number system, which makes it outside the scope of the syllabus and reserved for university courses in complex analysis.

That block one in the sample paper i was sure my solution was wrong but it was right haha
it just seemed so informal haha
Yeah I was working it out and it seemed so wrong lol but I guess thats why its a miscellaneous type question since its more logical rather than methodical

I mean thinking back on it, it makes perfect logical sense.
But when youre so used to doing it algebraically it just feels... wrong.
