that sheet in the ADEA.ORG website is wack. They do count +/- grades. However, if you go to a school like mine (university of washington) we use a point scale system. For example, we will not get an A on our transcript, but a number like 3.8, 3.9, 4.0. So we have to use another sheet given to us by our dental club to convert it (e.g. a 3.7 will equal a A- (or 3.667) and a 3.8=A (4.0) or a 3.4 will equal a B- (3.33)) So as you can see it may help us or hurt us, but luckily it helped me. 😛
I hope this helps. Don't focus on that grid that is the most screwed up thing. I was so confused after trying to figure that out.
Also, I would recommend making an EXCEL spread sheet and keeping upto date with your grades.
BCP = bio, chem, physics
Science =BCP +other

This way you will be on top and know how you are doing before getting AADSAS to do it.
