Hi,
I have written my GRE on April 30th. I scored a 140 in Quants and 136 in Verbal. I want to improve my score. I lack in geometry,probability,combination and permutation and ratios during school days,which affected my score at present. Can anyone help me in learning those concepts from the scratch? Or tell me how to learn those concepts.
I would be grateful if someone comes up with a good solution.
