Mcat prep from freshman year a good idea??

I am thinking of purchasing a MCAT review set so that while I am taking my pre-reqs I can challenge myself with review questions and prep while I take each class which will hopefully help in better preparing for the exam. Considering I am a freshman with a strong GPA for my first semester do you think this would be excessive? Thanks!
