Used to be good

Why is everything behind a paywall nowwwwwww☹️. This used to be a great resource for practicing questions from college board but now they’re just replacing all the questions behind a subscription. It’s no longer worth it to use this app, just use college board and khan

I hate how nobody knew about this app

Hey guys, this is one of the best apps that u can use as a student in the us or a student out of the us who is taking sat act ap college applications and even more things that I think they are going to add, it is amazing, the app support is amazing, one thing I LOVE about this app is that as soon as u send them a future that u wanna see in the app they would put it in the next day or the next week, I kid you not I had so many requests and they all had been granted so yeah I love love love this app. I would love to thank the creator who made it.


I would like to add the fowling futures
Can u add writing practice not just for English but just for general English skills, can u also please add ap pre calc because my teacher don’t teach ngl so I would like u guys to do that, I would also like u guys to edit the lessons for ap physics and that is because I need it to be more math haven’t and add harder questions so that everyone get to understand and make mistakes so that they ace the test lol

not good

can’t do anything without spending 100 a month smh

overrate sat resource

I tried using this to study for an upcoming sat but it’s genuinely unbearable. it’s constantly trying to advertise its pro plans (which are 81 dollars a months, genuine insanity) and it would barely let me get halfway through my study plan for the day before saying that i was out of orbs and had to stop for the day. you can tell that this is owned by a money hungry corporation rather than a user centered organization, and i’m tired of dealing with resources like this as a student. in my opinion it’s better to use completely free resources such as khan academy or the online blue book, because this will get you no where unless you have a lot of patience waiting for your orbs to reload, or a wallet big enough to fulfill their insatiable greed to desperate students money.
