Got a practice test score of 1290, but I want to get a 1500 on the actual SAT

Hey, so I am about to go to 10th grade and i was planning on taking the SAT in January 2027. I decided to take my first practice test just to see where I am standing. I got a pretty bad score of 1290 on my practice test, and I really want to improve this score and get it to a 1500. Im planning on doing the khan academy for SAT, oneprep, and purchasing a textbook for the SAT. I heard that the SAT is getting harder and harder, so I need help on how to prepare. :)
