Does taking AP classes or any classes in general in one year or another make a difference in college admissions?

Does it matter if I finish AP Bio and AP Chem in Sophomore Year or is there a difference in college admission if I take it in Junior Year/Senior Year/Freshman Year?

Also another question, I’ll be taking MultiVariableCalc in 11th grade and Diff Eqs in 12th Grade can I receive credit for that or will I have to retake it in college. I took Geometry H and Algebra 2H in middle school so will I receive credit for that?

What science classes will you take junior and senior year?

Regarding receiving college credit for MVC and DiffEQ, it’s a bit of a gamble. If you take those courses at a community college there is often a guaranteed transfer of credits to your state schools. For private colleges it gets more iffy. Some schools will give you credit, but often the most selective schools will only allow you to use them for placement. Some schools, like Stanford, I believe, will ask you to take a math placement test regardless of classes taken.

No. Although I would dissuade you from taking AP Bio and AP Chem concurrently. Just from a stress level, it would be better to split them up.

Depends on the college. An in-state public may give credit. A private college will generally not give credit. But some colleges, e.g. Penn, MIT, have internal challenge exams for credit. Other colleges eg. Princeton, Harvard, offer an advanced version of MVC for students with prior experience.


I’m not going to take a science class most likely in Junior Year unless I take AP physics C but that might be an overload so I just left science APs to only senior and sophmore year. I’m not sure if this is a bad idea.

My kids chose the order based on their intended major and class ranks implications. So take those into consideration.

The order doesn’t matter, but be sure to keep a rigorous schedule through Senior year.

AP Science Fr/Soph years and then core/non-Honors, or no, science class Junior/Senior year doesn’t look good. There’s no race to finish early.

If these are high school (not college or dual enrollment) courses, then you will have to retake them in college if needed for your major, although some colleges’ math departments allow for advanced placement by exam (although you may still have to substitute a more advanced math course in its place).

If they are college courses, then they are likely to be transferable to colleges, although colleges may vary on whether they are accepted for subject credit (versus wanting you to retake the course because the course you took is missing one week’s worth of topics or whatever).

If you do have to repeat those courses, some colleges offer honors versions that may be more interesting than the regular versions if you have already seen the regular version material before.

Some of it is about pacing. AP Bio and AP Chem are both a lot of memorization. Will you have enough time to spend on these classes if you take them at the same time?

Also, consider your teachers. Are they known to be good? Too rigorous? Not teach? My kid’s AP Bio teacher didn’t teach 3 of the 8 units during online/COVID. This left my kid to self learn these units. It was sheer agony. I can’t imagine if they had to do that plus learn AP Chem at the same time.

What did you take in 9th? What are your career goals? Will you major in STEM?

There seems to be a great AP bio teacher and both AP chem teachers are great as well at my school which is partly the reason to why I decided to do concurrently and still have relative interest and fun

Yea it’s just im not take an AP science in 11th grade. It doesn’t matter that much right? I’m just formulating for now no final decisions on my schedule for 11th.

Yea I agree it would be incredibly stressful, but I’ve heard both teachers at my high school are incredible teachers so I hope to not be too stressed.

Yes, it is - you’re supposed to take one science each year. Unless you’ve scheduled Honors Physics jr year, your progression would look “strange”. There’s also no bonus for taking a senior-year level AP sophomore year.
Your progression could include one AP science each year and Honors Physics alongside AP Bio, for instance.


It’s best to take a course load that shows rigor through 11th grade. Most kids find 11th grade to be their toughest year. When you apply to colleges in the fall of your senior year colleges will be looking at your GPA and courses through 11th grade. Don’t put it off until senior year. Kids who want to have it a little easier wait until senior year to do that. Don’t take your foot off the gas yet.

Yea true. I should take AP physics C!
