I did everything I could, still got 1450

I don’t know how to improve my score. I did everything right, I made an error log, solved it deeply, solved every hard college board question bank problem, solved 200 more, got a 1540+ in every bluebook practice test. How’d I still get such a low score? Is there any way I can get this to a 1500+? Please give ANY good tips that helped you if you were in such a situation.
