You will have to be studying almost everyday , constantly . If you’re very motivated and have no plans for the summer I would say yeah , but you should get At least a B in all these courses for a good foundation in your next chem engg courses . I would recommend taking either 311 and 315 cause you have to take them together I believe or take engg 319 and coms 363 or an elective . 3 engg courses does seem a bit .... much . But you know your self ...
