The grading scale for chem labs is very annoying but as long as you just complete the assignments, you should be good. The course is also heavily dependent on how chill your TA is. I took this course online but I found it to be pretty easy. Just remember to fill out your lab notebook as you go or write everything you plan to do before you start experiments. Make sure to ask the TA exactly what they are grading for. They will give no credit for forgetting specific things.

Follow rubrics, ask questions, do every assignment and you should be good.
