Natural Science fail

[Kaskadian]

I'd take a look at straighterline. You may need to check with your adviser to make sure the classes they have will work for you. They have quite a few different science classes available. In total I ended up taking 9 classes with SL towards my degree; I have a better time grinding out classes than doing tests. I'm not working until I move out west, so while being able to dedicate 10+ hours a day on these classes I was able to complete 6 of them (start - finish) in 7-10 days.

Take a look at the following links:
(Science) Online Science Courses for College Credit Transfer | StraighterLine
(Health Science) Health Science - Online College Courses | StraighterLine

I'm not trying to sound like a salesman for SL, but it's been very helpful for getting me through some difficult classes (managerial accounting, business law, etc). If you consider it's self-paced, you should be able to study a chapter and knock it out almost immediately. The majority of courses that I had to take were 6 tests; 4 standard tests, 1 midterm, & 1 proctored final. (no homework, no graded quizzes, etc).

Good luck!
