Replying to Help with School, +K

Alright so im halfway through my first year of general sciences but im doing a transfer to engineering. Right now I have all the credits i need to get into second year, but I'm missing a key physics. my options are

a) take 5 courses, wake up at 10ish every day, and still get to keep my job at a ski shop, ski one day a week, and then take 2 courses in summer school to make room for that physics class next year, less stress, more likely a higher GPA, but held down in the summer with less time for trips. (only part time at lifeguarding job which pays really well)

b) take 6 courses, wake up at 7am 3 times a week, most likely have to quit my job at the shop, ski one day a week, little to no free time, more stress, potentially lower GPA, but have a sweet summer and have free time to go to whis in april once the semesters done, as well as set me up for my second year. (Also have a lifeguarding job which pays $25 an hour in summer, starts in july)

im really stuck on this one.
My other courses are, integral calc, matrix algebra, programming, organic chem, and mechanics. Im missing calc based physics. Anyone with some input would be appreciated, ive never taken a 6 course load so im not sure what to expect, especially with difficult other classes. +K for helpful answers thanks guys
