I’m a junior, and I haven’t taken any AP classes because my school doesn’t offer them. As much as I wish I could take them, I go to a rural underprivileged high school where only one AP class is offered (that I’m taking this upcoming year.)
I’ve taken a lot of dual credit, but I’ve always heard this isn’t as good as AP. I’m feeling super frustrated at the lack of opportunities I have. Is there anything I can do?
From a college admissions pov, you won’t be at a disadvantage: you will be assessed in terms of what is available to you.
From a personal pov, if you are looking for more academic/intellectual/achievement stimulation, w/o knowing more about you & your circumstances all I can say is: follow your most genuine interest(s). Find ways- live or virtual to pursue them.
What classes will you take next year? One option would be to study beyond your school’s course requirements and meet the AP expectations, then take the AP exam. Another option is to take APs online. My kid has taken Calc BC through BYU and Physics C through UCScout. While not ideal, it allowed them to take two APs that their school did not offer.
What classes are you scheduled for next year?
What classes did you take?
Taking DE classes is excellent, it shows initiative, intellectual curiosity, wlingness to challenge yourself. Plus, the best indication a stusent will succeed in college is… success in college classes 
So, DE will be just as good as AP classes.
Beware, though: you should follow guidelines for your most slective colleges rather than the criteria for an AA/AS (depending on the State or CC, these might be quite different).
My planned schedule for next year is:
AP chem
DE bio 2
DE World History
DE Hydrology
DE Precalc/Trig
Honors English 3
Student Council
I’ve definitely thought about self studying for AP tests online. How much of a time commitment do you estimate it to be?
Before I address your question, where is your foreign language?
Since you are taking chem, bio2 and hydrology, have you had physics? Also, why take three sciences in one year?
I would also suggest taking CLEP Exams for subjects that are not DE. For example, you can take the CLEP College Composition exam and either the American or English Literature Exam. You could also take the CLEP Biology and Chemistry exams just as a back up to your AP and DE classes. While not all colleges take CLEP exams, many do. Just something to consider. 
Seconding the question about foreign language- competitive colleges will want to see level 3 or 4.
Have you had Physics?
Any way you can take Freshman English as DE?
I can’t take physics until senior year, and I’ve already taken all the foreign language i can. (french 1-3.) I am honestly just taking science because I love it. There isn’t a reason outside of interest.
i’ve taken three years of french but can’t take physics until next year. 
on another note, i’ve considered dropping hydro to do french four. i just love science so i wanted to be able to take a lot!
Great idea! I’d drop Hydro and take French 4. As long as you’ll fit in physics, you’re fine. Two college level sciences in one year is enough. Show the colleges you can handle rigor in all areas.
Self studying for APs is time intensive—why take them if you’re not shooting for 5s? As @MYOS1634 suggests, in your situation, where you’re primarily taking DE classes, you’re more than fine for rigor. The only reason to take the corresponding AP exams is if the college you will attend does not grant you credit or advanced placement with your DE credits.
Colleges are usually very clear with APs—get this score 
get these credits/placement. Some schools may quibble over your DE classes because they’re unsure about the curriculum covered. The advantage to having AP scores is that they’re more predictably useful when you get to college.
Thanks, I’ve been meaning to make the change so i’m glad you think it’s a good idea! My counselor has to be so tired of me changing my schedule at this point but it’s fine haha
