Online GRE Mock Tests - Reality Check

There are many free and paid GRE (Graduate Record Examinations) practice tests available both online and offline. But students find it difficult to choose as they don't know whether the test will be able to give them correct idea about their status of preparation. Now why are the tests not close to the actual GRE??? After all, there are questions and answers only :)

Most tests don't have the correct scoring algorithm. GRE test algorithm is not a simple one and it requires some research to figure that out. Most tests don't provide score in current GRE scoring format and even if they do, they may be in-correct if they don't follow the correct scoring algorithm.

As GRE is a sectionally adaptive test i.e. performance in first Verbal and first Quant section determines the difficulty level of second Verbal and second Quant section respectively. This brings up a very fundamental question. How can someone decide, whether a question is of easy, medium or hard difficulty level? We don't think one person can, as it is quite subjective e.g. a person good at probability may think of a probability question as an easy question but for someone else it might be the toughest one. Without the correct classification of questions, one can't create a correct adaptive test.

Most tests don't even have the correct mix of various topics and question categories in them. This may lead to a lot of surprises for the test taker in actual GRE.

As they say, "Untrained warriors are soon killed in the battlefield." The simulated environment in which you practice should be as close as possible to the real battlefield. This requires the test makers to understand how ETS is able to solve the above problems.

There is a lot of technology involved in coming up with the GRE tests. Its accuracy is of utmost importance as it is considered by the universities as one of the most important measure of the abilities of their applicants.

Most coaching centers have good faculty and they are good at teaching the subjects. They also provide set of questions, answers and their explanations to the students. However, because all the above real tough problems can only be solved by technology and data science (as ETS does) and which is not the core competency of the faculty of coaching institutes, they end up creating wrong practice fields for the students.

We at Wiseswan are bringing together the solution to all the above problems using data science technologies. Key points to mention: -
  • Wiseswan knows all about GRE adaptivity and scoring algorithms.
  • Wiseswan can generate a full length correctly adaptive test out of any 80 question provided by anyone and host on our platform.
  • It can calibrate the scores correctly and let the test taker know where he or she stands in terms of his or her preparation of GRE. We give detailed analysis and explanation on the questions too, so to identify one's weaker areas.

Currently there are 2 Free Quarter Mock Tests and multiple practice tests available for Verbal and Quant. There are many more to come very soon including free full length adaptive mock test.

Stay tuned for more ...

  1. Interesting to see how this will shape up in the future. At the moment, most people applying to B-school with the GRE are those who are also using their GRE scores to apply to specialized master's programs in other business areas
