Hello Sophomores! I hope that all of you are doing well and are staying safe. I am looking forward to getting to see you all again on the other side of this!
There are many different places to go for review online.
The familiar ones:
Khan Academy : https://www.khanacademy.org/science/chemistry
Spark Notes : https://www.sparknotes.com/chemistry/
A lesser known one (also some AP for you self-studiers out there who are testing this year):
Kent Chemistry : http://www.kentchemistry.com/
I know that there is a lot out there, but here are a few websites to get you started. I hope that you find these websites helpful and that you find any time you spend reviewing material both rewarding and reinforcing to what you already knew!
