Had to chime in … My 9th grader (accelerated in the sciences, top EXPLORE score etc…) originally started AP Bio but after realizing how picky the teacher was going to be on the lab reports, quickly switched to Honors Bio. He is definitely challenged in this course and can somewhat breathe … He had to find a balance with the class and also daily practice/games with his varsity sport. As a freshman he is also taking AP World History, which he absolutely loves for all of the enormous learning. Even though it's a TOUGH class for his GPA, it's his favorite! smile
