An annotation is simply a summary of a book, article, or some other written source. A bibliography is a list of sources on a particular topic. Put together, an annotated bibliography is a list of sources on a topic that offers a summary for each source.
The computer-delivered GREÂ® General Test takes about 3 hours and 45 minutes and consists of three separately timed sections: 1  Verbal Reasoning â There are two 30-minute sections, each containing 20 questions.  Quantitative Reasoning â There are two 35-minute sections, each containing 20 questions.
Each of the two scored Verbal sections you will encounter on the GRE consists of approximately 20 questions in 30 minutes â obviously, that gives you (on average) 1.5 minutes per problem, but keep in mind that during that time you will also have to read and process several Reading Comprehension passages.
