Stuck on what? For an undergrad, those problems can easily be solved by going online or to a tutor for a fraction of the cost. And that's for STEM based problems, humanities is all about flattering whatever opinions the professor personally holds.
The best piece of advice I got was from one of my english highschool teachers who told me a story about how when he was in university he was getting graded really poorly on essays until he basically regurgitated what he thought the the professor wanted to hear.
It's been a while since I've been to university, but I think it probably still holds.
Now back to my TPS reports.
Due to this he gave me opportunities to perform research in areas that I didn't even know existed.
Had I not gone to a university I never would have been exposed to these areas of technology.
Nobody will loan you money to do that, howvevr.
