Hello , I have just finished with gmat, got 680 , now I have to give Toefl, I have aprx 2 month, but i am completely confused as I have no idea from where to start! Please advice me what books to do and I wonder if there are some decent online toefl tests? My weak point is writing, and I am terrible at spelling! I would be very grateful if you advice some additional books for toefl writings and grammar as well~ cheers
