@AverageJoe22 Spending a lot of time studying and doing problems does not necessarily mean you’re good at math. The HW problems you posted also do not help your case…
To be frank, given the information you’ve shared it’s unlikely that your math abilities are as strong as you think / are portraying. Even if you were actually good at math and are just somehow terrible at standardized tests, you are still much better off applying to LSA because the CoE adcom will undoubtedly have the same concerns that have been brought up in this thread.
