SAT preparation resources

Hi,
So I am planning on retaking the SATs in October ( or september, the closest SAT date ) and I wanted to try some new websites. I have never tried any online resource as I have had a private tutor, but since I already have a 2250 (combined) on my first attempt, I am looking to at least get a 2300 or above. The good thing is I have the whole summer to prepare for it, It would be really helpful if you could share some online tutoring websites or resources.

Also, I just came across https://edrolo.com/ , has anyone ever used it? does it actually help to increase the score?

Thanks :slight_smile:

Anyone?
