<p>Depends on your high school and college/major. I coming from a high school with a great english program and decent social studies honors system with below average science and math going into ChemE at U of I was a HUGE WHOPPING DIFFERENCE. I can't stress that enough. Even with my strong ADHD tendencies I managed to get through high school working but barely (I don't want to say I slacked b/c I tried my hardest only b/c I wanted to but I didn't have to).</p>
<p>So coming to college with having never studied for a math test b/c "either you know it or you don't" (yeah that changed) or science test "I know what I'm doing in class sort of so I'll be fine on the test" (hell no) type of ideas vanished in the first few months of school. It was a big eye-opener b/c it was hard enough already but then I had to compete with kids from the best programs in math & science in the state! That was hard to know that I already had so much catching up to do that I couldn't b/c of my ADHD plus the fact that I was even further behind by not having a good math & science program.</p>
<p>So having said that I still managed above a 3.0 and am working toward a 3.5 I am very happy with where I stand b/c of my hardships and I can't believe I did it. It took a lot of work and everbody is like "is college hard?" Well you know what? Yeah, it's damn hard, but that's what you're paying for. I feel like I've learned more than 10x as much in one year of college than 4 at high school. It is incredible how much I know now.</p>
<p>The biggest changes (for me):
1) Math lectures are long! - In high school the teacher taught for 10-20 minutes and set the rest of the period for hw. Yeah lectures are long.</p>
<p>2) Math hw must be done regardless of grading. - Nuff said</p>
<p>3) Math, again, tests can be studied for and it requires endless repetition of problems and understanding CONCEPTS yes in math there are concepts. That was big for me.</p>
<p>4) Don't ever slack off in a gen ed - truly the biggest waste of time besides taking an unnecessary gen ed is doing worse b/c you thought it would be easy and slacked off.</p>
<p>5) High school help = stupid; college help = SMART - about OFFICE HOURS: treat them like a class.</p>
<p>6) Get to know your profs, TAs, etc. - They will like you more. Believe me. I don't care how much you hate them, if they like you everybody wins.</p>
<p>7) You are competing against the best and brightest, not stoners and others who although in honors have lesser career goals than you. - Nuff said again</p>
<p>8) Group studying in high school = socialize; group studying in college = lifesaver. - No joke, get to know people from the first day in class. You never know when you might need them.</p>
<p>9) Don't overload - If you are going to an excess amount of class and one isn't required, drop it. You have 4 years for a reason.</p>
<p>10) If you need help in any area, seek it fast. - My ADHD was eventually treated with the right amount of medication by halfway through the second semester. At least I had the courage to go at all but it still managed to wreak havoc on my first semester & some of my second. Now on something that I know I could have done better I am picking up the pieces (like a person who partied or gamed too much but it wasn't either so that makes it so much worse) and that is no fun. Lesson learned - if you need extra time on tests, etc GO AND GET IT. LEARN WHERE & HOW. Sorry but I can't stress this last point enough.</p>
<p>I will try and come up with more but that is enough for now.</p>
