IS CS 162 and 271 feasible for Fall.

Hey I was wondering if I could get any guidance from somebody that has already taken CS 162 and 271. I was Planning on taking both for Fall. I am taking CS 161 and 225 right now for the summer session and since I work full time I have just enough time to keep up with those 2 classes. What would the time commitments look like for CS 162 and 271 (also difficulty) in comparison to CS 161 and 225? Any advice would be appreciated.
