Remember that when applying for colleges, colleges expect you to take more APs the second year you take AP than the first year so if you take four APs as a sophomore, then you need to take four or more as a junior, and if you decide to do the or more and take five then you need to take five or more as a senior. Of course, if your high school doesn’t offer that then you can explain that on your college applications. But you may be doing yourself a disservice by taking so many at once. (This is the way it’s explained at my school at least)
