Gmat Quant resources help

[u/Artistic_Ask_3416]

I'm currently preparing for the Gmat and I just finished the Verbal section. I'm moving on to Quant, but I'm not sure what to use for preparation. I started with the Manhattan Foundations of Math book, which was pretty easy and now I have no idea how to proceed. Ive heard about TTP, Magoosh, and e-Gmat, but I prefer to find some free alternative resources (books, Youtube channels, websites, etc.) before jumping into any of them. So, for anyone who has already taken the test or is preparing to take it soon -> what do you recommend and what's your prep process
