First priority – make sure that you have memorized EVERYTHING. Then, go to and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on That’s always some good practice. Good luck – I’ll be praying for you! You can do it!!
