Is there anyone who have done GRE before?

Hey there! So basically I have just started my GRE preparation. Ia there anyone who have given this exam before? If yes, kindly suggest places in Lahore (Pakistan) or online from where I can purchase GRE international books like Kaplan's GRE book, ETS book etc

Or if you have any books and can give me for few months, do let me know that too. ^^

Thank you!
