<p>If I took honors biology in 9th grade and AP Chemistry & AP Environmental Science, is it possible to self-study for Bio E or is that not feasible without AP Biology background? If it is possible, does anyone recommend any really good prep books or guides? Thanks!</p>
<p>I think you can do self study and then take the biology e subject sat. You’ll definitely have a better advantage and probably end up getting a better score if you took the ap level course first. However, I did self study and took the bio e test after the normal biology course and scored around 700.</p>
