i failed out of uni so take my advice with a huge grain of salt. but its ok to fail or rescedule. as long as you persist ofc. I failed some class and the shame made me fail more. reality is pretty much everyone has parts of their studys that are boring or incredible hard. and pretty mich everyone fails some stuff. Just make a plan, figure out what made you fail last time (if it happends) and try to prevent that next time.

tl;dr: dont be like me. be open and honest to your friends, professors and family. and you will make it :)

what a non answer. imagin someone asks for directions, and all they get as an answer is “traveling isnt just beeing good at walking. you need to do the work and find the way”

I mean i totally agree with your observation, but op asked for tips. they are probably a younger person asking more experienced people how to start into life.
