This is a bit off topic, but I just wanna say a few things

.
For chemistry, I strongly suggest that you take CHM139 (Physical chem) first term and CHM138 (Organic chem) second term. The reason behind this is that CHM139 is mostly a review of high school (plus a few new things like the Henderson-Hasselbach and Nernst equation) while CHM138 is completely foreign to the majority of you all. You would have an easier time remembering high school stuff in the fall rather than spring. Also, you have to consider who is the professor teaching for each term. If you can, try and take both your courses with Browning because he has more experience teaching first years. This basically translates to a better experience when you write your midterms too since he knows how to create a test of appropriate difficulty

. Last year, those who took CHM139 in the second term had a 46% average for the first midterm (which overlaps A LOT of high school material) and apparently 80% of the class failed it. Usually, the first CHM139 midterm has an average in the low to mid 60s. Naturally they did a "bell curve" to raise it to 51% and it's still pretty low... I don't remember who was teaching the second term, but it definitely wasn't Browning. I'd also like to point out that Browning really shines when he is teaching organic chemistry. Lucky for those of us that took CHM138 the 2nd term, we had him for the entire course

.
Next, calculus. Now since MAT135 is a full year course, obviously you don't have to choose which term you take it in. However, I would recommend that you take it with Lam. He's basically the one that creates the tests and does all the administrative stuff for the course. Also, he's pretty highly regarded by his students. In fact, students from the other lectures try and sneak into our lecture because their profs aren't as good as Lam. This happens pretty much every year, lol. In the end, Lam had to create a seating plan (in university, lol...) because those that weren't registered in his lecture were taking up the seats of those who were registered. Sign up quickly because the spaces fill up FAST.
For PSY100, you'd probably have either Dolderman or Urbszat. They're both good professors, but they different sets of tests for the two classes. I had Urbszat for psych and he wrote the tests 100% based on the textbook. Heck, you don't even have to attend any lectures and you could get 85+ as long as you remember the textbook. As for Dolderman, he uses a lot of questions from his lectures but I hear he's very fair (ie, taking off unfair questions on the tests and bumping up marks).
As for BIO150 and PHY138 (or whatever the two half courses are) , can't help you there since everyone has the same profs.

So, if your timetable permits it, try and take it with these profs. You can find out who is teaching each term/lecture at
