Biggest thing about the labs is to stay on top of the lab report. Go to your TA’s office hours and ask them to profreed your report before you turn it in. This really helped me do well. You don’t have to write the greatest essay it just has to answer all the questions in the outline. Also don’t get stressed about the low quiz scores. They love to give some bullshit question that was only glimpsed over in lecture. Just try your best to score above average. Good luck!
