Take two APEX AP courses in 1 Semester?:Anyone here who has taken an APEX AP course

Long story short, I'm considering taking AP Physics B on APEX this fall.
The thing is, my plan was to take it this summer through my school's summer program and then take another APEX course during the school year. Things happened, now it's too late for me to start a summer course.</p>

<p>What I want to know is, how difficult do you think ti will be for me to take 2 APEX AP courses this semester? Anyone have experience with that? Please let me know what you think/what it was like.</p>

<p>Thank you in advance for your time. :]</p>
