freshman year

does anyone have any tips on freshman year ?!?! im supposed to be a sophomore but i got held back in 6th grade due to some family stuff and living situations, i was also in a special education room for math in 8th grade which means im gonna be in 8th grade math for 9th grade but i still highkey suck at that too so any tips on subjects would really help and are appreciated, but i also need some tips on social stuff, im not like a total friendless person im pretty known among my grade and age group i would say, like im not popular i used to get bullied alot but im also not like a a total quiet kid whp just sits in the corner of the room.

  im like super high social anxiety though, i hate presentations and stuff like that its so nerve racking being on public display. like im fine with sitting at my desk and reading out loud but like answering questions infront of a class or doing a presentation is actually terrifying, i mean well i think ive gotten better at presenting stuff ngl because usually theres the kids who are annoyingly loud and then theres the kids who like dont really speak loud and u can barely hear them, id say im right inbetween those two, i just go up and get the presentation over with… 

  honestly im still pretty awkward though because whenever im asked a question while presenting i never know the answer and usually just look at my friend for help, but i know in highschool im probably gonna have to do some solo projects so pleaseee help me out.
