Let me put it this way: you only really need to know high school level math for the quant portion of the GRE.
...Added to the fact is that there are no calculators...
I think once you finish the section you can go back to any prior question. Just write down the ones you skipped.
Unless ETS has changed it's policy, I don't think you're allowed to go back to prior questions. That is, in effect, one reason why they use the 'adaptive tests' where the questions being asked depend on your performance on prior questions. As a result, unlike the paper-based test, each question on computer-based version isn't weighted uniformly.
What Eugene is saying is that the computerized test gives you questions based on your current performance. So, if you get the first question right, then the next one will be a little tougher, and will carry a greater weight on your score. If you get the first question wrong, then the next question will be easier, and carry less weight. Therefore, you can get the first 10 or so questions right, and you're almost at an 800. However, if you get a few questions wrong on the front end, then you will likely not get close to 800 even if you answer the rest of the questions right.
With this in mind, you can gauge your performance based on the level of difficulty in the questions your are asked. By close to 800, I mean 780 or above.
If the starting point is X and you get a -Y for an incorrect answer and +Y for a correct answer, then in both the cases you are at X+10Y.
I don't understand the logic behind this.
Case A
You get first 10 questions incorrect, the next 20 questions as correct.
Case B
You get first 20 questions correct, the next 10 questions as incorrect.
If the starting point is X and you get a -Y for an incorrect answer and +Y for a correct answer, then in both the cases you are at X+10Y.
