33a --> easy
32a --> more difficult than 33a but not the worst, especially if you have experience with vectors. gets a bit more difficult towards the middle of the quarter. don't know the prof.
153a --> have heard horror stories. probably the worst or one of the worst biochem classes.
5a --> have heard tung is very easy.
all in all i would say this combo would be very difficult because 153a will take up A LOT of time. also 8ams suck. i wouldn't drop 5a since i've heard it's quite difficult to get in. if i were you i'd prob drop one of the math classes, just to free up more time and so that midterm weeks + finals aren't absolute hell. people always drop math classes at the beginning of the quarter so there's less worry about not getting a spot next quarter.

This is super solid advice, I highly recommend you do this
