<p>What I would do is to study solely for the SAT I now (during the summer), and then, when you get home from your test in October, start studying for the SAT IIs. Just study as much as possible for each testing date that you have coming up; don’t start studying for your SAT IIs until immediately after you take the SAT I in October. It doesn’t really matter though, since either way you have to study pretty intensely starting now.</p>
<p>You don’t necessarily need to study all day every single day for the SAT I, but you more likely do for the SAT IIs (since you only have a month to study for those if you heed my advice, and since they are more based on knowledge and specific subjects that you need to know thoroughly), so I recommend that you do most of your college research this summer as well–i.e., in between your studying for the SAT I. This way you don’t have to worry about college research as much while you are studying for your SAT IIs. Get it? I think if you don’t slack off at all, you’ll be fine. I definitely think it is possible. The fact that you already took those subject tests before means that you are already familiar with the test. All you need to do is study as much as possible and as efficiently as possible.</p>
