It was time for my next big thing.

StraighterLine made it very easy and convenient to take all the prerequisites I needed to take to advance my career in Science. I liked how flexible it was. I would highly recommend it to anyone.

Things I love about StraighterLine

Time for me

I was able to fit classes into my free time and spend 10 hours a week when I was available.

Variety of courses

I took five courses with StraighterLine and saved thousands of dollars on my degree.
