<p>It's absolutely beyond impossible to answer your title question, because we have no idea how smart you are, or what major you will be. The only answer I can give you is that you will probably have to work very hard to get a 3.5, let alone higher.</p>
<p>For a typical class, there are weekly problem sets. Core physics (ph 1 and ph 2) sets usually have 4-6 problems. I've seen math sets range from 3-6 problems in ma 1, and ch 1 sets will usually also have 4-7 problems (however, classes do change, and it's been a year since I was a frosh). In my experience, problem sets freshman year could take anywhere between 3 and 9 hours, depending on how smart you are, how hard you work, and how much of it you've seen before high school (note: this absolutely does not imply if that you are smart and hard working that every set will take 3 hours). Sometimes the problems are from textbooks, sometimes they're not.</p>
<p>Freshman courseload is pretty standard; ma 1abc, ph 1abc, ch 1ab, bi 1, 2 frosh hums, ch 3a, a MENU course. Bio oriented people take Bi 8,9 instead of Bi 1, EE's are recommended to take EE 51, 52 to get it over with on pass fail, some math/ACM majors do the same with ma 5. CS oriented people take CS 1. There's course a catalog and undergraduate handbook online that should say what all the courses are and have some more info on graduation requirements if you're that interested.</p>
<p>Some advice? Enjoy your summer before Tech, don't do something silly like try to prepare for classes. Spend a lot of time getting to know houses during rotation, it's far more important than that Ch 1a set due Friday. Use pass/fail, meaning, use the fact that you don't have to do/finish every single problem to pass. Spending 4 hours on that hard proof you still don't understand even after office hours and your friend explained it to you is not worth it. To further clarify, for a 30 point problem on a 100 point ma 1a set, if you can get 15 points for 15 minutes work on that problem, and to get the other 15 is going to take 3 hours and 45 minutes more work, take a hint and let it go. Don't be a troll; keep your door open. Pick a major you actually like. Don't take hard classes or pick a hard major to try to impress people; you're probably just going to get wrecked if you do.</p>
