GMAT club tests are really focused and up to the mark tests. In addition to challenging Quantitative questions and to a large extent helpful verbal questions, the look and feel of the tests are very similar to exact exam. The practice gives you the feeling of a real exam and the options of practicing questions in test or practice really makes the experience of solving the questions significantly worthwhile.

I would highly recommend that students who want to improve their overall score (along with sectional score - Quantitative from 49 to 51 and Verbal from 30 - 37/38) take these papers and revise all the book marked questions religiously.
