I took the GRE on October 2nd, 2018. At the time, I was staying in Chicago for a visit, and knew that it would be wise to take the GRE while in the US - mainly because of date availabilities.
I registered for the GRE only a week before the actual test, and didn't really study a lot. Mostly I just read up on what the question formats were, and what the GRE examiners look for in the analytical writing section. I also read on how the test center works so I wouldn't be caught off-guard. I only actually did one mock test, and that was for the paper-based test.
I was taking the computer based GRE, so I was able to see my quantitative and verbal scores immediately after finishing (probably in record time! I only took about 2.5 hours to finish the whole thing). I had gotten a 164 on my verbal and 168 on my quantitative sections. The results for the essays came in about ten days later - I had gotten a 4.5 on that section.
Overall, I'm pretty satisfied with this result. From what I've seen, these are really good grades, and I didn't actually work all that much for them, so I'm very happy with my scores.
