I am preparing for GRE and I have qualified for SSC CGL Tier-1 exam. I have hardly a week gap betwen GRE and Tier-2. How should I start with my preparation so that I can score well in both? I'm a B.tech final year student.What should be my study plan for cracking SSC CGL 2016 tier 1, if I start preparing now? Will I be able to score 150+?
