<p>The Biology Subject Test matches up with the AP test, except that the Subject Test is 86147826814X easier. No short answer(arguably the hardest part of the AP test) and the MC are much simplier and easier and covering slightly less content. I would recommend taking the June Subject Test (or the May one ONLY if it is after the AP test which im not sure it is) because once you study for and take the AP test you literally dont even have to study for the SAT. I took the AP test in May and studied a ton for it and then in June I took the SAT subject bio test and studied 15 minutes the night before and scored a 790 (shoulda been an 800, YEAST IS A FUNGUS not a prokaryote haha)</p>
