This is a possible feat.
I myself studied for 37 days total (approximately 200 hours total.)
You will have to make some sacrifices though.
For me, it was no more video games, no FB, no social networking, going on SDN only once a week(even to this day I limit myself when to be on SDN), and no hanging out with friends. All I did was workout, went to class, study, cook, eat, urinate/defecate, and sleep, literally. Some people thought I died or something due to my long absence. Discipline is critical for this.
Did I regret any of this? Not really. From a cost-benefit standpoint, the benefits clearly outweighed its costs. It was a part of my future being on the line. Just think about this: Your friends won't be paying for your bills, but doing well on the DAT can open up doors to where you can.
But honestly this greatly depends on your background. I took the DAT having AP Biology, AP Chemistry, Organic Chemistry, Genetics, and Biochemistry I & II under my belt along with many other unrelated chemistry courses(which I thought didn't help, if any).
You will need to map out exactly what you need to study and gauge their corresponding study time.
One thing I can definitely tell you is to worry about yourself and not about others. This is quite distracting, and it will take a toll on your confidence (you will definitely need this on the exam.)
