Hi. I am considering having both my 9th grader and 10th grader do biology next year, but they are on different levels. My rising 10th grader is currently doing Novare Physics in 9th grade and his younger brother isn’t quite ready to do that. I would prefer to use Berean Builders for my 10th grader but my 9th grader needs to have the audio available, so I was looking at doing Apologia with him. My question is this, if I have them both do different biology curricula simultaneously, can I just combine the lab for them and have them both do the same labs from, say, Berean Builders? If anyone hasn’t done this specifically, is there anyone who has used these two curricula to be able to compare the labs? Or is a biology lab a biology lab? Thanks!
