Hey... I took GRE few months ago... It's kind of challenging questions especially the English one... For me I love math so I did good at Math but didn't get what I expected at English... So from my experience you have to take at least 4 weeks to practice ... For the English take time to stretch your vocabulary... For the Math just exercise some questions... I used resources from YouTube and from Google... I can share details if you want... Good Luck😊!
