So there are a lot of threads about school, what to major in, etc etc. I decided that I will post some of my experience in college, lessons learned, and takeaways. Use it if you see it fit. feel free to disagree:
Pre-college
I started college a year earlier then everyone else in my class. Thinking I was uber cool, I graduated in 3 years(rather than 4). I did the minimum requirements to graduate high school, got the minimum ACT/SAT scores to the local university of my choice, and went to college. It wasn't until I stepped into college that I knew how underprepared I have been.
tips: If you get to pick your courses in high school, pick advanced and AP courses. Take the AP exam if you can to waive some courses. Do more math, physics, chemistry then the minimum standard. College for a freshman is very fast paced. So you need to prepare in advance if you want to succeed. Dont worry so much about protecting your precious 4.0 highschool GPA. I think(not 100% sure) that it is better to take harder classes and get a B, then to take a bunch of blow off classes and get an A. It'll at least familarize you with higher level thinking and material.
Picking a major
I started as an MIS major for 1 week because I could not pick a major. I then picked computer engineering because I liked computers. After that, I picked electrical engineering because I did not like programming courses. Then I picked math because I wanted to graduate on time.
tips: It's okay to change majors, but pick it for the right reasons and make up your mind quickly. engineering is about building and designing things, but most of your courses will not be about building and designing things. You get a lot of math, physics, chem, mechanics, etc etc.
If you are having trouble with a class, you have 2 options: 1)study harder and ask prof for help, 2) change majors. If you know you are not doing well, and feel that you will not get better, and don't want to get help, dont stick it out. change majors to something that you know that you can do well. You'll ruin your transcript if you dont. If you are destined to change majors anyways, do it now and do it quick.
classes and professors
A lot of prof's will seem like jerks to you. You'll hear horror stories of the class average being a D, etc etc. If you hear this, then you should be smart and start building rapport with your professor from week 1. Go to their office hours for questions on homeworks, etc etc. Most are more than willing to help. Dont be shy about seeing them. Group study is okay, prof's are way better.
For classes, dont take too many courses per semester. I took 6 courses one semester, and I ended up dropping a bunch just because I wasn't doing too well in all of them together. take what is reasonable. Or better yet, if you can afford it, take 1 or 2 courses less during the semester, and make up the rest in summer.
no cramming! It might be cool to say that you studied till 5 am, but it is not good for your health. study every day, + the chapter of the next class.
jobs
I worked sales, and made okay money. but in the end, my grades suffered.
If you can afford it, dont work unless it is related to your major. when you apply for a real job, not a lot of people care about your sales job at the Mall. Instead, seek internships. these are way more valuable.
If you must work, work on campus. you might have time to study.
college life in general
I understand that this is college, it's your last 4 years before you go to the real world, etc etc etc. However, You are preparing yourself for the real world. If you screw up college, then you will be under prepared for the real world. So while you had fun the 4 years in college, you might struggle the rest of your life until retirement. Dont go in with the mentality that this is your last chance at freedom.
college is very important. You need to do good to succeed if you want the rest of your life to be easy. Ease off on the bars, frats, girls.
final thought
Be realistic. You need money to survive in this world. Dont pick a major just because its your love. Think about what will happen after graduation. Most of you will end up knocking up some one(accident or on purpose), so you will have a family to feed. Find a major that you like, and can make good money. Have a plan for where you want to work. Dont just wing it. This is college and you need to have a sense of urgency.
Graduate on time. Dont hang out too long. I can tell you that the 'real world' is tons better then college. sure you work 8 to 5, but once you finish, the day is all yours. no homework, no exam.
