Don't let people psych you out when they say that this or that is 'hard'. Often times they are just trying to get you to feel admiration for them.

University builds on High School. If you can do the problems at High School then you will more than likely be able to do the problems at University. First year, in particular, is quite a lot like High School with respect to the level of the work. They allow that students are adjusting to being away from Mummy and Daddy and being in lecture halls of 200+ students instead of being in small class rooms with a teacher who knows your name.

The physics people I know... Say to think of mathematics as being a bunch of tools for your tool box. So you need to figure out this or that for chemistry or for physics... So you reach into your tool box and see what mathematics tool will help you. Pythagoras theorum or stuff about the sin of the angle theta or whatever whatever... Maths is just a bunch of tools. That helps me with my maths anxiety, anyway. Instead of thinking of 'Maths' as this big scary black nebulous thing that I can't possibly catch up on... I can learn this trick and that trick and the next trick in order to do the problems that I'm required to do for chemistry or for physics. Then over time... I can apply the trick I learned over there to this other problem over here. That's the only way I need to learn maths / the only use I have for maths. That kind of maths is fun.

I think most people have a hard time with maths because of bad teaching at some point along the way. Pretty sure my primary school teachers couldn't do maths, either. Not entirely sure why I didn't just learn my times tables the way I learned to read or hit a tennis ball or whatever else... But, anyway, it ain't so bad. Hardest thing at Uni is that you might not be able to ask someone (due to the sheer number of students who are struggling)... So you have to get used to Google being your friend...
