I'm considering on taking the ACT after the SAT. Can sm1 explain what is ACT to me, and how it works?

This may be crazy to know but...hey trust it'll help you a LOT. E()eryone is appreciated. There is no dumb answer. We are all in this together! We are SAT lol. WE should help one another whene()er a fellow member gets stuck in a question. We all should be supporti()e of one another! Good luck to those taking the SAT in december! You got this. :). Tips: Please don't be so hard on yourself. Also get a good night's rest the day before your SAT. It'll gi()e you more energy to be able to get those questions right. :)

I made a stupid mistake while signing in on the ACT website I basically wrote my first name TWICE in a row 💔 And whenever I'd try to register(or log in) for an upcoming exam it would straight up say this bs (on the 2nd picture) I changed my password for 3 times in a row bc I thought I forgot my password

Hru friends I might take the next trial for December Anyways here's my study plan type shii
