Some science classes do not require a lab, or the lab may be optional. For example, the school may require you to take 2 science courses, but only one must have a lab. So while labs are offered for chemistry and geology, you took the lab with your chemistry class, so you fulfill the requirement and do not have to take the lab with the geology class.

So, for the classes you took, simply count up the ones where you were in lab and see if you have enough units to meet the entrance requirement for the college of interest.

Hope this helps. Best wishes.

for each experiment, you collect data and submit a report (possibly just one per group rather than from each student) summarizing what you did, and how and why your results agree or differ from theoretical expectations.

if you don’t get stuck in a group with a bunch of idiots, you probably only have to stay in the lab long enough to get your experiments done rather than the full assigned period, but as you surely know by now, each instructor sets his own class policies.
