How many AP classes/honors should I take for a competitive school?

What science did you take this year? Why not take Honor CHemistry next year if you took Bio this year?
I would not jump to AP Bio as a sophomore in general.

Don’t worry about other people on CC. You need to know how YOUR grades are, what your school’s class sequences are, what APs are offered, etc.

Generally you are not expected to take AP classes as a sophomore…esp. if the only honors class you have taken is Honors Geometry. AP Classes are the equivelent of a college class so no colleges are expecting that as a sophomore. You may be ready for APUSH next year, or maybe Junior year. Don’t hurry.

Look at this and make sure you are taking what you need to.
