All About GRE Math Subject Test:
Introduction:
The GRE math subject exam is one of the GRE subject tests, which basically tests the capability and potentiality of a student's mathematical skills and abilities so as to get admission into prestigious graduate schools of the USA.
The GRE math subject test, which is a standardized test, when taken along with the GRE general test actually helps those candidates who would want to pursue higher studies in the field of mathematics and related fields connected with math. There are many schools in the USA wherein they accept the subject test scores. It is like an added advantage which makes the candidate stand distinct from others. But it would be a smart move to check and double check whether the University, you prefer accepts the subject test scores.
Please note that this test is not a replacement for GRE general test, but instead can be taken along with the general test giving extra footage highlighting your skills and knowledge in the math subject.
Totally there would be about 66 questions with a time limit of 2 hours and 50 minutes. All are multiple choice questions with five choices to pick from. It has only one section, unlike the GRE general test which has many sections.
ETS:
The GRE math subject test too is being handled by the ETS (Educational Testing Service). GRE Math Subject Test from ETS.
Difference between GRE general math and subject math test:
There are definitely some differences between the two tests. Students must not get confused with the two math tests.
 The math section of GRE general test checks the abilities of the candidate's understanding and application of basic mathematics not higher than high school level. General math test paper includes basic concepts like algebra, arithmetic, probability, etc., but the math subject exam tests a candidate's indepth knowledge of math concepts. It includes higher concepts like calculus, differential equations, etc.
 On a comparative note with the GRE general exam, which is taken on computers, this test is purely a Paperbased examination. Since it is not computerbased, the score of the preceding question does not reflect on the difficulty of the succession question. This is one of the advantages of using a paper based test, as the questions are fixed for everybody and do not change with the person's answering ability.
 There is negative marking in GRE math subject test whereas there is no such scoring in the general math test.
 No multiple sections as in general test and so no breaks offered in between.
Need for subject test scores:
 Apart from the master's degree, people who apply for the doctorate program would definitely require subject test scores, say for engineering, statistics, obviously higher studies in mathematics, etc.
 Some prestigious schools say like Stanford University, University of Notre Dame, etc. always ask for subject test scores.
Test score range:
For one correct answer, the score increases by one point and for every wrong answer, it decrements by1/4 marks. Once the total score is calculated for the 66 questions, it gets converted to a scaled score in the range of 200 to 990 points.
The students must be careful in answering the questions as there is negative marking as mentioned above. Therefore it would be a wise gesture to leave it blank rather than to fill it up with guessed answers.
Once the scores are ready, it would be available online. The scores stay valid for up to 5 years of time starting from the test date.
Using the ScoreSelect feature, the best scores or all scores would be sent to the Universities as per the candidate's wish. More on ScoreSelect from ETS.
Once a request for the scores is made, it takes minimum 5 working days for processing. Therefore, if the validity period's expiration is nearing, make the requisition for scores way before, say at least a week to maximum three weeks in advance.
Good and bad test scores:
A good score would be above 770 to 850/990 with a percentile of 75 to 90 and on an average basis, around 700 for admission into the Ph.D. programs. More than the score, it is the top 10 percentile, which is considered as best score and bottom 10 percentile as lowgrade scores . Generally, the schools opt for the top ones. Check out with the schools for their cutoff percentiles as ETS does not categorize the scores as the best and worst ones. The bad ones could be in the range of 100s.

Test centers:
There are GRE math subject test centers all over the world. Before registering, do check out for the date and the test centers near your location. Paper based test center list
Registration process:
The GRE math subject test is conducted three times a year, during the months of
 September
 October
 April
But only one subject test is allowed on a particular day. For 201718, the registration opened on July 1st, 2017 and ended on March 2, 2018. The registration for GRE math subject test ends one month before the test date, April 14th, 2018.
There is a late registration facility available too, which has an extended period of a week with late fees of $25 extra and is available only online.
Registration is a very simple process which can be done either online or through regular mail.
Online registration:
An ETS account needs to be opened. If there is an account that has been already opened for GRE general test, then the same account ID can be used.
A very important point to remember is the name used while registration must be exactly the same as the name in the identification document that the candidate carries with her/him while attending the test.
The name issue is no joke, as the student may not be either allowed inside the exam hall or the scores could get canceled if found later on after the GRE math test is over.
There is a video on how to register; please check out Video tutorial and for the transcript of the video

Test preparation:
Practice makes a person perfect; therefore, the best key to success is practice, especially with mathematics. With more practice definitely there will be an increase in the GRE math subject test scores. The GRE subject math test would definitely not be hard for someone who has practiced well. With more hours of practice, there will definitely be an increase in the scores.
One of the best ways to prepare for the GRE math subject test would be to revise whatever was taught in the college level, and also have a quick look into the high school math books for basic algebra.

Grading Princeton Review:
Princeton Review has been helping and tutoring students for nearly more than three decades ranging from a simple homework to GRE, GMAT, CMAT tests, etc. The list is really very long offering tuitions, publishing books, etc. They are based in New York and critics have made charges against them that the final test scores do not match with what has actually been advertised.
But still, it is a wellestablished serviceoriented organization guiding students with their exams.
Answering the question paper:
A smart way of handling the question paper would be to choose most familiar and confident questions first, then not so difficult ones and then if time permits the students can try their hands on the hard and most difficult ones. All the questions carry equal marks; therefore, it would be a smart gesture to attempt familiar ones first.
Usage of calculators:
During the test, an ETS calculator will be provided and personal calculators will not be allowed inside the test center. Therefore, do not take calculators or any other electronic devices into the examination hall, as the candidate could get expelled if found otherwise.
It is a very regular ordinary calculator that is being provided by the ETS and not scientific. But it is always a good practice to workout using the scratch paper space provided along with the question paper than depend on calculators. Use calculators for complicated subtractions, divisions, etc and not for every simple arithmetic calculations.
Mathematics:
Just because the content syllabus of the paper is vast and the books reviews are a bit scary, that does not mean the paper is going to be tough and difficult. For a pupil who has mastered mathematics since high school, this multiple choice question test would be definitely interesting and confidently challenging.
After all, math is a very interesting subject provided the person has a strong knowledge over the basic ideas and concepts. This test is just to judge the fundamental and also indepth knowledge of the candidate.
Other subject tests:
Apart from mathematics, there are other subject tests too like Biology, Chemistry, Physics, Psychology, and English literature. Click here to know more on them .
