Does anyone know any good Algebra 1 studying tips. Big tests coming up.

Review your notes, make flashcards, go back to your textbook and solve problems you haven't solved. Just keep doing practice problems

same i have 9th grade psats coming up. what ive used to study are these following apps:

symbolab - gives a detailed explanation of any topic and they have another app that gives you questions to solve called symbolab practice

Algebra touch - this is a lifesaver there are structured explanations on some math topic

cymath, socratic and mathpapa - if you ever get suck on a question or you dont understand it solves it for you and also gives a step by step explanation

if you are taking the psats like me, i would recomend trying the pre-tests on khan academy to get an idea of what to expect. i hope this helps and good luck :)
