How important are senior year classes for applying ED?

I’ve applied ED to UPenn, but something that’s been on my mind is whether the senior classes I’m taking rig tnow have a big impact. Of course, grades for these classes aren’t sent, but they still see what classes I take. Currently, I am taking

  • AP Physics C Mech
  • AP Bio
    -Distance Math at Georgia Tech (Dual enrollement)
    -british literature
    -online, on level econ (this is because there’s no honors econ available and because of the physical education class I need to take 2nd semester, so there wasn’t room for ap micro/macro econ, but colleges won’t know this)
    -orchestra (highest orchestra, concertmaster)

Junior year I took 4 AP Classes (chem, physics 1, lang, bc calc), orchestra, and honors spanish, so it’s not like my rigor was bad. Would the online econ/ literature class (since its not AP Lit) have a negative impact on my application? Or am I overreacting about it

The question is academic as your application has been submitted. If your GC checked the “most demanding” box, it’s unlikely that the AO will parse your transcript semester by semester. The rigor rating applies to the entire 4 years, not just one year. If your GC did not rate your schedule as “most demanding,” well, it’s too late to do anything about it now. Good luck.
