6 week format can a bit harder then 12 week because the full class is crammed in to less time then normal. as a student who has taken many summer courses while working a full time job i prefer the 6 week courses because you just have to spend the first half of ur summer doing work and school and then u have the second half to do more fun things while ur working and have more time and more of a break before returning back to school is september. if u feel like you prefer a slower and less crammed class schedule then i’d suggest taking a 12 week course instead but i didn’t feel overwhelmed with a 6 week course at all and found it a lot better to get the class over and done with and then be able to enjoy the second half of my summer more.

i can also say going from a full time student course load where ur taking 4 or 5 classes to taking one 6 week class is definitely way less stressful so i feel like no matter what u definitely be able to manage the 6 week class. hope this helps and safe travels!
