Self Studying Question...

<p>For those of you who have been studying for or taken them in the past, how hard would it be to self study AP Euro, AP Bio, and Ap Chem at the same time next year, and how much time would it require?</p>

<p>AP euro would be no problem whatsoever, bio is pretty much memorization so that should be doable, but time consuming, and i have no idea about chem</p>
