Studying 650 hours for the March SATs

Thanks to the difficulties of the exam system in Turkey, it is a bit hard but funny for me to study English and (easy-mid level) math for 11 hours a day, also my efficiency does not decrease easily while studying, I allocated 600-650 hours of this 980 hour study time for the SAT exam and my goal is 1460 points, you guys think it is way too much for my goal?? Note: My English level is C1 and my math level is intermediate Also I translated this text with google translate cause im tired, ignore if there is some mistakes, thanks. Also i'll solve 45 SAT mock test ( bluebook, khan, ex college board exams, etc. )
