Hello all, I am new to this site and taking the Prereqs to get into WGU through Straigherline in SoCal. I am about to sign up for the AP I+LAB today and saw this post about another site to purchase the lab kits. The $500+ for the kits for the labs are a bit much and I'm thinking of purchasing through the hometraining tools site...would someone be able to tell me what to purchase exactly from this site? If I can pay less for the kits that would be great.
