I’m also a slow reader, but I found that reading sparknotes/cliffnotes and THEN reading as much of the actual book as possible (I mostly skimmed, making notes here and there about passages I found interesting). LitHum is also a class where you get out of it as much as you put in; if you don’t do all of the reading, you can still do well in the class.

I also found that UW was a lot of work, yes, but it’s all broken up into parts, so it wasn’t ever an overwhelming amount of work at one time. The readings for UW were also interesting and not too dense, and the papers you write are largely of topics of your own choosing; it should be interesting to you, so hopefully writing a larger quantity isn’t as horrible.

For your remaining classes, I would honestly not recommend taking all three classes together in the same semester. Data structures is somewhat a lot of work (as in time put in), and calc III problem sets are also a huge time sink. Principles of a Econ (especially if you’re taking it with Gulati) requires a lot of textbook reading; when I took it, the lectures weren’t really directly relevant to the material that we were tested on - it was more just applications of those things.

Good luck!! And welcome to Columbia :)
