Liberal Arts are what were considered the backbone of an education.
They include all of the humanities, most of the social sciences, all the natural sciences (physics, chemistry, and biology), and mathematics. So having a passion for all subjects is great, but you need to translate that passion into academic success.
If your GPA is already low, taking on more classes will not help you - it will make things worse for you. You need to focus on the classes you are already taking and do better at them.
Here is the thing - if you are not good with high school math, you will not succeed in any of the natural sciences. All need, at very least, algebra, geometry, and college-level calculus. Physics and chemistry need more than that. It will be the same for social sciences, as well.
Of the long list of courses that you are proposing to take, three require pretty strong math skills - AP computer science, AP research, and microeconomics. Even AP environmental science requires a decent amount of math. You are also, at the same time, taking geometry.
If math is difficult for you, you will not really have the time to keep up with these three classes and pass them, much less do very well on them. On top of that, aside from these classes, you are proposing to take five additional courses.
These are too many classes, and if you try to take them, you will either have to drop at least half, or you will fail at least half. By the time you realize that it is too much, you will likely be falling behind in all of your classes
Figure out your strengths, and focus on those classes. Take no more than 6-7 classes, and no more than 4 AP classes. Do not take college level courses that require a lot of math.
In which classes do you have the highest grades?
