TCN modules, podcasts from Doc C (you can download them for free in the itunes store), electronic peer network, practice exams, mayoclinic.com, a&p text book, flashcardexchange.com, mosby's medical dictionary. Use your content outline to make sure you have all of your bases covered. Probably the best way is to just get the texts and do the reading assignments. But money is an issue for me so I have to make due. TCN is overrated if you ask me.
