i want to be a gynecologist?!

You would have to improve your grades. Maybe I am out of date having gone through med school in the early 1970's, but you had to have a least a 3.5 GPA in college to have any chance at medical school - unless you were African American and a woman since they had quotas for these. Minorities could get into med school with much lower grades. A white male in the USA had better have top grades. And in high school you need grades adequate to get into college. When you start college you should preferably be in a science major such as chemistry or biology. I was in chemistry.

You could do it if you tried. I teach history in college as my retirement plan from cancer medicine. I have met no dumb people in college. ( Politically correct, ain't I ? LOL ) I have met many students who did not try, did not study or read, did not attend class, and did not turn in assignments on time. If you are a compete slacker who will never try, forget medical school. I think you could do it if you were willing to work. So many people these days seem to feel "entitled" to good grades, good jobs, and good money - without having to do any work. I did the work for the good grades. I never saw the big money as a cancer and blood specialist doctor, but I was never in it for me and money.
