Today in class we learned about the composition of isotopes. I do remember learning these things freshman year but I did not actually retain the information so it was nice to go over it again. This information would've made the pretest last week significantly easier.
I agree evan! I vaguely remeber learning about this stuff freshman year, but for the first time ever, after today i actually understood isotopes and feel very confident in my learning. and i agree knowing this would of made the pre test easier, ovbiously
