Below are my personal opinion, take it with a grain of salt

All of the major are difficult in their own perspective, but math subjects are compulsory for all IT degree courses, you cannot avoid studying it.
i remember correctly most subject for all IT degree student are same in year 1 and maybe first half of year 2
my idea is that if your taking IT as your degree, the university made math a compulsory subject in 1st year for very obvious reason, because you will need it in other related subjects in 2nd and 3rd year

I am not majoring in CS so i would not comment on that, but I never thought of learning something completely new could be easier.

You have prior knowledge about math, even u don't know how to solve it, at least u know where to go to find the steps to solve the solution, just pick up from there
that won't be hard. Its going to be hard if you are clueless on 80% of the thing


For me personally, its better to concentrate and study on the math question that you are not clear, worrying whether you can do it or not does not improve the situation.

Either way, i would like to say sorry in advance if i being too harsh on you.

Hope you are able to get some good input from the reply here. Are you joining MMU?
