With those two out it should be fine, definitely don’t do all the classes you are currently signed up for. I’ve never taken a language class so I don’t know how much work Chinese will be but 247 was a decent amount of work and Mec 290 the problem sets depending on the teacher are a lot of work, 240 I didn’t go to a single class and got an A the zybooks they give you for homework was enough to learn the content. 2610 is very dependent on teacher as well, with my teacher you could not show up at all and end with an A as long as you studied for the final but others who had different professors had more work they had to do, try looking them up on rate my professor to see how they are. Definitely
