Are you taking these classes now? If you have all of these classes left, it would probably be wise to do them over 2 semesters. This would put you at being finished with the pre-reqs in the Spring of 2010. Have you taken the DAT? If you haven't, study during the spring semester of 2010 and take the DAT in the early summer (May/June). This would be for the application cycle of the Dental class of 2015 which begins June 1st, 2010, which would mean you would be starting D-school in the fall of 2011.
