If I self teach myself a subject, would I be able to get a credit for it?(Btw, I’m not taking dual enrollment anytime soon, I’m in 8th grade) What subject should I teach myself(I want to go into medicine.) Lastly, how would it look for college?
They tend to care less about self study than classes. The exception is homeschoolers.
Focus on taking a rigorous schedule in high school. That’s more important.
If you take the corresponding AP/IB/CLEP exam, score high enough, and the college you attend gives credit for AP/IB/CLEP, then yes. But if you end up attending a school like Harvard (the subject of an earlier post of yours), which will no longer give credit-by-exam beginning with the class of 2024, then no.
None; take a challenging courseload within the curriculum offered by your school.
They are beyond unimpressed.
When you get to HS I suggest you focus your time and energy on the following:
–Working hard, learning, and doing as well as you can in the most challenging curriculum you can manage.
–When the time comes study for standardized tests.
–Get involved in activities you care about and work towards making meaningful contributions to those activities.
–Enjoying spending time with your family and friends.
To give another side to the snarky responses: I self studied Latin, AP Stats, AP Comp Sci, a discrete math course, and calculus, because I was interested in those subjects and it made sense in context (e.g. I had no opportunity in school to take the class). This was on top of taking the most challenging course load I possibly could at school, which, as previous posters have said, should be your priority. My point is that self studying isn’t bad or unimpressive, as these posts are suggesting, but it should stem from your desire to learn the subject, not for college.
That was uncalled for and beneath you, IMO
The OP specifically asked if it would look to colleges. “Not impressed” is what I was told by AOs.

Are there valid reasons to self study? Yes. Did the OP say that that s/he wanted to do so to scratch an intellectual itch? No.
@skieurope @happy1 Don’t fight 
Anyway thanks for you’re responses as well as for you @lookingforward @chercheur
In general colleges don’t care about what you do on your own time in 8th grade. While it is too early to commit you can see if your high school has any summer programs for incoming 9th graders. If you have a local hospital you can see if they will take volunteers your age (I volunteered back in 8th grade but I think where I live you need to be 16 now). If you have a local nursing home maybe you can do some volunteering with the activities department. This can prove more beneficial than self teaching.
If you want to learn for the skate of learning look at coursera, edx etc but these are for personal learning.
Think about what colleges are looking for.
THey want people who are prepared, who are involved in their community, intellectually curious, who will come to their college and hopefully pay for that privilege.
When they determine who to admit, they look at GPA, SAT/ACT, course rigor, Extra curriculars, Essays, etc
THe first 3 are the most important.
So first, take challenging courses and do well in them. If your HS doesn’t have courses you want/need, look at your Community College.
Get involved in your community…do service…join clubs, etc.
If after that you have time to self-study…then great. You might be able to get credit for it.
If you can take an AP test (or the like), and if you can get that AP test result before you apply (taking it Junior year), then you could say that I have a 3.78 GPA, all this ECs…and I self studied ABC and got a 5 on the test.
But if it is a class you can take in school…I would not bother.
Eons ago the National Science Foundation funded our school for independent study projects under the direction of one of our science teachers. We got school credit for it. It was a regular class where you researched your own project. Check to see if anything like that is possible at your school.
