Yes, I think you over-interpreted. I was pointing out your challenges that you could improve on.
All of your stats were not in one thread, so I more I saw of them, the better grasp I had on your chances.
In second statement, I think you were in pre cal, wanting to take Calc AB over BC and I was encouraging you to take AP calc BC over AB if your school offered it.Engineering is looking for readiness for the major and BC covers all of AB plus other topics. On the AP test, you will get an AB sub score. My son had an A in 151 all the way until the last 10 days of the semester, until the last semester exam and final (which were 10 days apart). It was much tougher at the end and only 5 questions on the test. It will also look better on your app if your school offers BC and you have it listed to take on your apply TX application.
I want to see you accepted into engineering and I want you to have as few struggles that could possibly be eliminated now.
