hmmm interesting.
well I'm sorry you've had a rough start in your first semester but you're just like everybody else. so did I. it's normal. it's a huge adjustment from high school and most students start to adjust after 1st or 2nd semester.
they're realizing that college is not like high school where you can get by everything half-ass and pass (meaning - studying just couple days before exam or doing everything at last minutes). college is where you're actually paying professors to teach you something you need to learn for your major.
college is 100% optional. you are free to decide whether or not to go to college and you are free to decide whether or not to take a course (but you'll have to complete that course if it's required for your major).
your parents should be more forgiving to you. I really dislike the fact that you are living under fear. that is not healthy and productive for you. right now - college is your responsibility, not your parents. you need to keep up with everything by yourself and you'll have to make sure of everything by yourself. keep track of everything. always ask for help if you're struggling or have any question - your professor or tutoring center. go see your professor during his office hour as listed in your syllabus. do not worry about asking a lot of questions or taking up his time. you are paying them thousands of dollars to teach you so you get to ask all you want. there's no such thing as "too many questions". if your professor has a problem with that, then you can take it up to your academic dean and he will take care of it and put that professor in his place
Many professors are always fearful of deans
because deans keep track of everything such as pass/fail statistic.
if you have any personal issue and you need someone to talk to, you can either contact your academic counselor or student counseling center (or typically called as Student Affairs).
colleges are required to abide by federal law called FERPA... meaning everything about you is strictly confidential. So that means your college will not disclose your information if your parents request for it such as your grades.
and lastly.... remember - your college handbook is your "bible". it lists EVERY information and procedures for you to know how to deal with most situations. please do take a long moment and read it - from cover to cover. it will tell you everything you need to know. if you know your college (professor/faculty member/etc) is wrong, all you have to do is point it out in your handbook and they will immediately amend their mistake.
