I will be kinda honest however....
for me, high school <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< college.
Seriously, the classes o high school were SO BORING compared to college. they are longer, but they are SO MUCH USEFUL! Especially considering I'm doing a technique, I actually love computer science so much that I LOOK FORWARD to the theory classes.
Which makes me think that the increased amount of work you do worth it, but in the end, I feel much more accomplished than high school where it was almost free time everyday....
Basically, college is harder except if you like it because in this case, it's not that hard and it;s more enjoyable than anything
