Anyone on here made bad grades in school and made it through college?

I got in trouble a lot for farting loudly in class.

I had a 2.0 in high school. I took classes that suited my skills in college but was very fortunate to scrape by the first year putting in, literally, minimal effort. I had to drop a math class but still passed all my courses otherwise. I improved 2nd year and finally got my ish together by my third year. Managed a 2.5 GPA my final year in college, which was a substantial improvement from my freshman efforts academically. If I took tougher courses my first year, I may have been kicked out/failed out. But who knows, perhaps harder courses would have motivated me to work harder.

JFK was a C student and did okay until he decided to visit Dallas ( always a mistake ).

My grades weren't quite as bad as yours, but they weren't great, either. I had about a 3.0. Luckily, I was really good at standardized tests. I managed to do well enough that in spite of my grades, I won a significant scholarship to attend a top university where... again I earned mediocre grades. I had about a 3.0 again. My ability to do well on standardized tests again saved me and I rocked the GRE which got me into a pretty mediocre grad program where.... I finally got my ish (as you say) together and earned good grades. Now, I'm giving the grades out as a professor.

American education is distinguished by its willingness to give students multiple chances. It's not over for you by any means. But, you're going to have to figure out why you can't make yourself do the work that's necessary to succeed. Is it because you lack the discipline to do things you don't like? It it because you're afraid that if you try you'll still fail? Could you have ADD or some related issue that makes it difficult for you to sit and study for long periods? Think hard about what's getting in your way and work to overcome it. It sucks that we now live in a society where finding a decent job depends almost entirely on your performance in school. 40 years ago you could have just gotten a decent factory job and lived a pretty decent life. No more. You're going to have to figure it out. Don't be afraid to ask for help, either. Better to admit you have a problem and get it fixed, then to suffer the full effects of it for the rest of your life.

Good luck.

I had a 1.9 to 2.5 in high school. I ended up getting into a decent but not great school because of running and overall did very mediocre. Maybe 2.5 to 2.9. I was out of college for a little then got a masters degree from a mediocre school getting a 3.8 GPA.

I always did well on writing and not taking tests. Sitting around taking tests always bored me but if I could express my ideas I did better.

I recently finished that and am making around 70k my first year at my job.

I got a crappy GPA in undergrad because I didn't really work that hard (3.6 cGPA, 3.5 sGPA), but I still managed to get into med school. Started working hard in med school, and have been near the top of my class through my first three years. Don't let a crappy GPA deter you. I am proof that you can overcome a rocky past to accomplish great things.
