It depends.
In Texas, college admissions are decided by class rank June Junior year. Senior year course selection is taken into account depending on the major but for a non selective major, a high rank is sufficient. If they’re top 10% (or top 6%) they’re okay.
However, it isnt sufficient if students are aiming for UT, a selective major (especially CS, Engineering, Business), Honors college, or an Out of State College.
Overall, in order to be competitive at selective 4-year colleges, you need
- 4 years of English, with 1 AP if possible
- Math through Precalculus Honors or Calculus (honors, AB, BC; Precalculus + AP Stats is okay for Humanities majors but Calculus is prefered, and exected for STEM/Business.)
- Foreign Language through level 3, 4 or AP
- Bio, Chem, Physics + 1 AP science (one of these for STEM, APES if Humanities/Social Science)
- 4 years of History/Social science, including 1 AP if possible
- an art class
- other classes that reflect your academic strengths and interests
That being said, highly selective colleges expect 6-8 APs TOTAL. Taking 6 APs senior year is meaningless wrt college admissions and is likely to cause burn out. So, a senior year with all 5-6 core classes (as presented above) including 3 APs, plus a fun class you’ve always wanted to take (like Culinary Arts, Current Events, Theater Tech, Shop…) is 100% fine.
