I am 20 years old and received a bachelors degree in biology this past may. I am currently on a gap year working as a optician and technician in an eye clinic and have been working there for about 2 years. I have a 3.5 accumulative gpa: non science 3.8 science 3.2. I am about to finish chads videos and start studying for the next month for my OAT. I took my exam before and did not do well because I did not put time into studying at all because of my busy schedule and ended up with a 270. I changed my entire study method and I will be doing a bunch of practice exams and problems as well as going into detail. Do you think 4 weeks is enough to study and do well and what is the best study tips you have that will be able to help me especially for physics and chem. I would highly appreciate your help. I am aiming for a 320 + also how can I purchase practice exams through kaplan?
