/sci/ - Science & Math

First year CS student here, I know most of you already think we are brainlets when it comes to math, but hear me out.

We started with discrete maths - proofs. Like a lot, there's so much of proofs and professor goes so fast through lectures I'm left with notes, but no logic behind the steps to answers, since you must understand and gradually know how to extract shit and re-arrange it.

While I find it hard (we never did this in high school), I also sat down, learned and got a feeling for it and see things and how they happen, but I still can't put stuff into words a lot of the times.

Is this just because I'm facing a lot of new stuff or should I record lectures and go over them later. As said, we go through an insane amount of stuff in 3 hours and you gradually forget stuff as you go along, since there is so much new shit and new proofs that I just can't keep up and 90% of class also.

I did good in hs math, but feel complete brainlet, but I'm not sure if it's because it's new math to me or if the professor is just going too fast and let's out the steps.
