A) GRE
The GRE is a prerequisite for most US and European universities and is meant to test your basic mathematical and verbal skills. It consists of 3 sections: Quantitative, Verbal and Analytical Writing Assessment (AWA). The total duration of the exam is around 4 hours with a ten minute break.
Quantitative. Maximum score: 170. This is your average high school maths. The topics covered are given here. This section is a simple one and does not require rigorous practice. However, don’t be overconfident. Practice moderately, don’t make silly mistakes and you can get a 170.
Verbal. Maximum score: 170. This section is tough, especially for people who don’t do much reading. It involves going through long confusing passages and answering questions to which all the choices seem plausible. You will also have to memorise colloquially unused vocabulary to answer these questions. You can check out the type of questions asked over here.
AWA. Maximum score: 6. As the name suggests, this one involves writing essays. There will be two tasks with 30 minutes given to complete each one. The pattern is always the same. The first one is “Analyse an Issue” and the second is “Analyse an Argument”. You can find more information over here.
One thing to note is that you will have either 3 verbal and 2 quant sections or vice versa. However, only two of each will count for your score. The extra one (you won’t know which one) is an experimental section and will not contribute to your score.
