"Relearning Math from Grade 1 to Pre-Calculus on Khan Academy" Any Suggestion or tips?

As the title suggests, we're currently on Christmas break from December 17 to January 6, and classes will resume after that. We'll start with Statistics, Probability, and Basic Calculus. My foundation in math is a bit weak, but I'm strong at recognizing patterns and memorizing, and I really enjoy solving problems because I love math—it makes my brain work hard. I'm planning to relearn everything from grade 1 up to pre-calculus, including algebra and trigonometry. Do you think this will be enough for me to breeze through basic calculus?
