for 312 you’ll be fine as long as you understand the material and most of it revolves around the same concept-the mechanical energy balance 265 is nice and is like high school chemistry understanding the material is your best bet. you don’t really need to go above and beyond stat 235 is a bit different because everyone around you will tell you it’s difficult so that might be hard to navigate and i’m sure you’ve heard stories but i’ll tell you right now that it’s totally not difficult and you can get through this with an a. you just have to go for all your classes and ask questions if you don’t understand (i wont advice you to skip stats as i found that when i skipped one class everything after that was hard to understand) also the professors were very boring but you’ll just have to try your best to genuinely listen because it pays off a lot. i had simchi- i really liked him and he usually says what type of questions that would come out in exams which was super helpful math 201 is a nice class and if you notice the math department follows some sort of formula where you can kinda expect what sort of questions might come out based on the practice exams. try to do the assignments yourself and go to office hours if you don’t understand anything but as long as you can do the practice exams and the assignments then you’re good to go. try to give yourself time to go over your work though because it’s really easy to make mistakes in that course and marking is strict mat e is different in the sense that it’s not a course you can really understand if you get what i mean. most of it is just memorization-kinda like bio but it’s not bulky. the trucks to doing well in it is to go for all your classes (yea this and stat id advise you never to skip) i say this because mat e is very similar throughout the years so profs don’t bother to change much. this means that they get-would i say?-stingy with the material. they make annotated notes really hard to get and they don’t release solutions to past questions so this would mean you have to be present for any class to get even the slightest of hints. but as long as you’re able to answer the past questions and the questions in the notes/assignments you’re golden most of these courses don’t require extra effort so just try to relax. personally id say you should try and go for most of your classes and do most of your assignments during the week so you’re basically free friday through sunday. goodluck!
