I guess it depends on the APs and your aptitude/interest in them. About a year ago I asked this same question here on CC. My daughter (junior) is taking 6 APs and doing really well, so it is definitely possible. She is taking Calc BC, Physics C (Mechanics), Chemistry, English Lang, French, and CS Principles. To be honest she seems to have less work than last year (sophomore), when she only had 2 APs (Calc AB and Biology), plus honors Chemistry, English, World History, and French.
