I need a bit of advice on a few things

I am having trouble deciding what I want kind of path to take senior year course wise and am stuck between going for hard challenging courses that I will most likely get a B in but they are still AP and the other option would be taking easy honors classes like French 1 Honors or Sociology Honors so that I wouldn’t have trouble but still raise my GPA which is currently at a 3.8 on a 5.0 scale. Keep in mind that I really want to go to UPenn but I dont know if it is out of reach or not. All the courses I have taken and respective grades are:

9th and 10th Grade Courses:
Anthropology-A
Russian Studies-A
Algebra 1B-B+
Physical Science-A-
Graphic Design-B+
English 9H-B
German 1H-A-
US History Honors-B+
9th Grade Health and Gym-A
Algebra 2-B
Geometry-B+
10th Grade Gym-A
AP Macro- B- (3 on the Exam)
German II Honors-B+
Global Studies Honors-A
English 10 Honors-B-
Biology Honors-B-

This Year I am taking:
AP Euro
AP Lang
Chemistry
Orchestra
Gym
Mythology
Psychology
Pre-Calc
German 3 Honors

Next Year the Hard Schedule would be
AP Stat
AP Lit
AP US Gov
AP US History
Chemistry II
Physics I Honors
Gym
Orchestra

I plan on taking SAT this March, May, and in October 2016. I will take SAT Subject Tests in US History, Chemistry, an Literature. And I will take the ACT next school year sometime.

To be honest, with your GPA is a reach (maybe less so if you get a stellar SAT/ACT score), UPenn is a reach. Sorry I don’t have any helpful advice to add on the class selection though.
