So i’m planning to take GregMat subscription along with the ETS official GRE books (offficial guide, verbal book, quant book). Also planning on taking the manhattan 5 lb.

Wanted to know if i should also take the manhattan seperate books for verbal and quant. Like are they useful and worth it or not?

also If the GRE big book is still relevant. Lot of older posts mention it being useful but no much information recently.

Thank you.

Planning to take gre in 6 months. Is it better to join a coaching?(If he's which one) Or is it better to self prep
