I sucked at math in high school, still suck at it! I'm a physicist tho! The trick is to accept you suck and that it's going to be hard. Don't get discouraged by those who find math easier than you do. We're all different, and you don't have to be the next Einstein to be a scientist, you just have to be motivated and able!

In case you think I'm exaggerating, I scored in the ~40 percentile in the Quant section of the SATs, 40-50 percentile on the GRE. Failed linear algebra the first go round (dropped it after the first midterm when I scored a 15%). Still went to grad school for physics. I'm now a successful physicist working on some really interesting projects, with a ton of opportunities, and with just a master's!
