Well.. I usually score perfect on my labs, here's what you should do: Before you start your lab, just outline it like a essay. Include stuff such as purpose, hypothesis, data, calculations, results and discussions and stuff.
For results and discussions, just say something about your results. I'd suggest you apply some kind of statistical test on your data, that'll get you 90% of the points on results and discussions for sure:)
Well.. you just need to sit down and read. I'm reading 3 chapters a day off of my organic chemistry book right now. (gonna finish it before my term starts in 3 weeks:) ). Remember to take notes when you read.
