^E=mc^2 is a physics thing.... not chemistry I believe
If I were you, I would drop out of the course.... It's too late for you, even if you have a chemistry tutor teaching you...If you are confused on how things are (especially with the introduction part of chem), you will struggle throughout the semester... If you stay and flunk the midterm you have a long road to get your grade high (unless ur teacher curves or drop the lowest test grade) because you have to learn the basics and also keep up with the lectures... Happen to me once in Physics due to an adjunct teacher, should've dropped it but I didn't
... Retook the course with a better professor (and put in more effort) and got a high B
Other options
-Go to ur college's tutoring center and "live there" (use up all their available hours), think about nothing except Chemistry for the entire week.. I dunno about ur college but some tutors won't bother helping you if you have no idea where to start.
-There might be someone in your class who retake the class so ask them what the layout and questions that might be on the exam
-There is a slim but possible chance that someone in the class might have the answers to midterms (you'll be surprise, but it does happen in college)
-If you are able to have a cheat sheet, by god fill that paper up with example problems and pray
The only thing I know about chemistry is adding/subtracting electrons (valence shell stuff), periodic table and some atomic weights addition, and how to turn a base/acid to a base/acid.... But that was in HS
... Thank god I don't have to take it in Electrical Engineering Tech.
Overall advice from a fellow college studentDrop out the class and find a better professor at
http://www.ratemyprofessors.com/.... Might be the student's fault but some Professors are just bad... Might receive a small part of your tuition if you drop sooner.. BUT think about it and weight your options, if you think you can pass the course and you study like a god than all the luck to you!
