<p>I’m a senior and I am debating which subject tests I should take. I took chemistry when I was a sophomore, I did very well, but I do not remember too much from it. I feel like if I got a review book I would be able to do it. I am taking AP Physics 2 right now but my class has not covered any modern physics, nor do I remember too much from waves. Which would be the best subject test to take?</p>
<p>Modern physics (relativity, wave-particle duality, etc) is BY FAR the easiest part to learn by self studying using review books. If you’re comfortable with all the other areas, you shouldn’t have a problem.</p>
