If you take 203, 280, and a Chinese class this fall, that shouldn’t be that bad.
If you want to take 381 and 482, then next semester, take 281 and 370 together. That will already be quite a lot, so then if you think you can handle more than just the minimum full time load, take stats 250 or 412 (takes care of your stats requirement) along with another easy class. 482 should be doable with 376 (as long as you can avoid Prof. Shi from what everybody says).
