I'm desperate, help!!!

Hey guys, I hope you're all good. I failed my first TOEFL test (got 83/120) and I booked it for the second time. My goal is to get 100/120. Can you help me? I checked many videos os youtube and materials, I'm also taking mock tests, but I'm still struggling in reading part (20/30) and listening (20/30). Also tips for the other sections are welcome, for now I am getting 24/30 for writing and 22/30 for speaking. I'm desperate, I appreciate a lot if you can help me! I see many people getting good scores studying for 1 or 2 days, which strategies are they using? I'm really sad with my scores because I know I can communicate well...
