My recommendation would be to study both simultaneously. Maybe to break it up, alternate days between verbal and math. When you're studying, do not just cover a topic and then move on from that topic. Every few days, go back and do problems from topics that you have already covered. For example, if you finish going through a chapter on ratios. After you finish another chapter covering a different math topic, go back and do some ratio problems to keep the content fresh in your mind. Once you add another chapter, go back and review the previous two chapters that you have finished. Do this all the way up until the test. This will ensure that the information remains fresh.
