LA class and Dental Materials Lab

Well I dont know about all of you but math is not my best subject!!  The math we learned for LA seems simple if only I could figure out how to do the calculations in my head!! Ah!!!! I have some studying to do.  I hope I am not the only one! Any ideas how to make it easier?   Then in Dental materials lab it was a great review to make models and trim them up and make cleach trays.  It was also fun to learn how to make temporary crowns.  Now we will all be able to do them when we get out into the work field.  Well my goal for this week is to study LA and get the math and all the calculations memorized! Wish me luck!!
