If you're only interested in micro and pharm, then I would suggest going for a topic specific resource. both picmonic and firecracker cover more than micro and pharm so you're paying for those as well, and you're not going to use them according to you. For micro, a lot of classmates say FA and Uworld are enough. If you still feel like you need help, microcards and CMMRS have been suggested. Good luck with your studies.
