Struggling with SAT

Hey guys

so I’m currently scoring between 1800~1900 on my two previos SAT real tests and I’m just wondering are there any test prep tips (esp. for the reading section

And I’m also considering taking the ACT at the same time, and does a roughly 2 month prep of act possibly get you a score of 32 or 33

Hope you guys have some advices to provide

Thanks!
