GPA: are those your own calculations or your school’s? Many colleges recalculate the GPA to suit their own needs. I do not know how BC recalculates GPA, though I’d be interested to find that out, if anyone has asked the admissions office.
AP European History has a reputation for being a challenging course. In my kids’ school, it is typically taken by seniors. It sounds like you are giving it your best shot! Keep up the hard work, but don’t worry - it is not unusual for a bright student to feel doubt when encountering a level of challenge not experienced before. As you begin next semester, ask your teacher and other students for study ideas. See this as an opportunity to learn more efficient ways to conquer a course, ways that will help you with the greater challenges you will see in the future.
Science for 11th grade: while BC’s website does not specify, many colleges will expect a year each of chemistry and physics. I would make sure those are taken before, or alongside, AP Environmental. At my kids’ school, chemistry is a prerequisite for AP Environmental.
ECs: in the future, consider adding service and/or having a job when you are old enough. Each can have its own benefits for your personal development.
As you mature through high school, consider the extent to which the Jesuit educational vision appeals to you. The BC website contains a “pocket guide” to Jesuit education that you might explore.
