5 Courses + 14h work

Hi.

I have a 14h/week contract with my job and I'd like to know if I should do 5 Courses during winter or 4. Currently, I am enrolled in 4 psych courses and 1 soc course. In addition, I live in an apartment which adds certain responsibilities.

I'd like to know, for those who are currently in this situation, do you still manage to excel in your courses ?

Thanks !
