The best material to always use is the official ETS books. Here you can see the books I recommend for Self-study. I highly recommend you to ALWAYS USE official material from the ETS http://www.gremathtutor.com/faq_gre.html
Once you get the books and have a feeling of the test, then you can decide if you need a tutor to coach you for the test.
BE AWARE OF MANY TUTORS ADVERTISING FOR THE GRE® WITH NO EXPERIENCE.
Hire a tutor with experience teaching the GRE®.
Many times I have had students spending a fortune with tutors that are excellent with their math skills, but not familiar with the test format.
6)How long should I study for the GRE® General Test?
The answer is very simple, you do not study for this test, you PREP for this test. If you have 2 weeks to take it, then you have two weeks to PREP.
If you have 6 months to take the test, then you have 6 months to PREP.
“Prepping for a test requires a plan , a checklist and a deadline”
Before registering for the test, determine how much time you have to prep for the test. Taking a sample test on the official website will help you determine how long you should prep for this test.
Which test is harder
the Sat or the ACT?
This blog summarizes the difference for math sections for the SAT and the ACT.
The SAT® and ACT® have different structures.
Many students find the ACT® to be easier because:
All the questions are in a multiple-choice format.
You can use a calculator for the whole math section.
The questions are shown in order of difficulty.
However, many students find the Sat® to be easier because:
The SAT® is shorter because it has two sections instead of one.
The SAT® math might be easier to conquer than the math of the ACT®
SAT® Math sections:
The Sat® Math section is divided into two sections, a calculator and a non-calculator section
The questions are formatted into multiple choice and grid-ins.
There is no penalty for guessing on the multiple choice questions.
The questions are not shown in order of difficulty.
The math section is divided into four sections: heart of algebra, passport to advance math, problem-solving and data analysis, and advanced topics.
Which math should I study for the SAT®?
You should really concentrate on understanding functions, linear equations ( y=mx+ b), solving basic word problems, basic geometry, and data analysis. There are some trigonometric questions for the test, but they are just basic trigonometry (SOHCAHTOA, degrees/radians conversion, understanding angles and its co-terminals (only for the sine and cosine), and understanding the transformation for the sine and cosine functions.
An example of the same question for the SAT vs the ACT
For example, the ACT will ask you: for the following function F(x)=3x+40 find f(2), while the SAT will ask you “A rental car charges 40 dollars a month plus 3 dollars per mile drove. The cost function is C(x) = 3x+ 40, where x is the amount of miles. What is the total cost if the car drove 2 miles in a month?”
Both questions have the same answer, they are both functions.
The ACT is more direct than the SAT for the math section.
How can I decide which test is better?
The best way to decide which test is better is to take a practice test for the SAT and the ACT and see for yourself which one you feel more comfortable.
