So I made another post to explain my position, and I need to learn Algebra 2B this summer (The B part or second half) In order to test out of it next school year and then take trig. So I was wondering if anyone knew a good source to self teach algebra 2B, maybe an online course, or a website that goes over all of it in a way where you could learn it well enough to test out. A free Online Course of some sort would be the best. If not any of the already mentioned, what else? Thanks.
