Need More SAT PREP

Hey Guys I am a current Junior who is worried about taking the SAT that is soon to come. I have been doing the 6 practice tests on college board but I still seem to getting the questions wrong. I do understand the ones I get wrong but I still think I need more practice tests from like collegeboard or something similar. I do have the kaplan tests but I do worse on those. I calculated on my practice tests and it came out to be an 1040. I am really smart with 3.85 GPA and I am not really bad on standarized tests I usually do good. Is there any way I can get more practice to improve my score? Cause my hopes are to strive to a 1300-1500 because I need it to get into the college that I desire. Please help.

You should review your practice tests and see if there is a certain section or type of question you seem to be missing a lot. Go through all your wrong answers and figure out why you got it wrong and a better way to approach it next time. If your issue is lack of material you can maybe use the PSAT practice tests (there are 2) to help you.
