Hi all,
I took the GMAT last month and scored 780 (Q50 V47). This achievement was heavily influenced by the hard work of the people of this forum, so I decided to give back a little and share a few well-known tips that worked for me.
1. Study planI took a month off work to prepare for the GMAT and established a gruelling, 12-hour a day study routine, as I was told that the test is extremely challenging. This is an important point, as I am aware that most of you won't have the same luxury of time that I had.
I started my preparation by taking the GMAT Prep test and identifying my initial weaknesses and areas I definitely needed to brush up on. That said, the first week and a half of my prep was really reading heavy, I did not do many questions, rather invested the time to go through all the Manhattan strategy guides and get familiar with the many question types.
After I'd gotten through all those books, I started doing the questions. I would spend whole days clearing official and unofficial questions, analyzing my mistakes and ensuring that I knew what I did wrong. I kept count of the number of questions I did during my prep and it stopped at 3100. Whatever you say about the GMAT, it is still a standardized test, and once you get familiar with the knowledge tested, doing questions is essential. If you get a question wrong, analyze your mistake and do two more of the same type.
Finally, the last week or so was almost completely dedicated to prep tests. I sought out all the free resources available and built stamina, at the same time deeply analysing my performance.
2. TipsAs mentioned earlier, my tips are ones that you have probably seen multiple times on this forum, however, I feel that if I started preparing now, these would be most useful to know.
Max out SCThis is crucial. I noticed a lot of people on this forum easily get Q51 or 50, but struggle with verbal. SC is a strange part of the GMAT, it doesn't really fit because it really can be trained to perfection. There are only so many grammar problems that the GMAT can ask you to solve, and they repeat so often. Go through the Manhattan SC guide once or twice (with full understanding), and then do as many questions as you can, preferably reading Expert Opinions, whether you get them right or wrong. You might feel that you're wasting a lot of time on one section, but it is really worth it because these are invaluable easy Verbal points. If you do enough questions, you will reach a boiling point at which any SC question thrown at you will contain problems you have seen a hundred times before and you will almost solve them with your eyes closed.
Don't spend too muchGMAT is a huge business. I would advise anyone not to spend hard-earned money on too much prep. There are many free resources available, this site being the best example. Manhattan strategy, OG and this site is really all you need. Don't think that spending $1000 on prep alone will boost your score, ultimately no amount will help if you do not put in your hard work. And if you really put in the effort, all these resources will be a waste of money.
Practice test-takingAs I mentioned, the last week of my prep was devoted almost exclusively to taking practice test and ultimately I found it very useful. If you are aiming for a top BS, you have to acknowledge that the substance of GMAT is not very complicated. It's the crazy time limitation that gets us all, strategy guides will help with all the knowledge required but not really with that. You have to build the stamina so that your score purely reflects your ability and knowledge and is not affected by stress of answering all the questions in time. I took a lot of practice tests and did not pay a dime for them:
1. 3.09.2018 GMATPrep 1 720 (Q47 V44)
2. Veritas 1 720 (Q48 V41) - Veritas is one of the best IMO, and with GMATClub you get two tests free.
3.
Manhattan GMAT 720 (Q49 V39) - OK, but the harder questions do not resemble the exam that much, especially in Verbal. Still one of the best you can get.
4. Economist GMAT Tutor1 750 (Q50 V44) - I felt the Economist tests were really pretty good
5. Princeton Review 710 (Q46 V42) - Good practice
6. Economist GMAT 2 760 (Q51 V44)
7. GMATClub CATs 710 (Q48 V39) - great practice but really hard, don't get attached to the scores
8. 800Score test 790 (Q50 V50) - really, really bad. This is the only one that is not worth taking IMO.
9. Veritas 2 760 (Q51 V44)
10.
Experts' Global 750 (Q51 V40) - strange one, not in the top of free tests IMO.
11. GMATPrep 2 (day before the exam) 770 (Q50 V46) - I would advise to take a GMATPrep test the day before the exam. It is a really accurate estimator of your final score and 99% of the time you will get within 20 points of the score you get the day before. Suddenly the stress of not knowing how the test will go is gone :D
28.09.18 Official GMAT: 780 (Q50 V47), IR 8, AWA 5.5.
Ultimately, take as many practice tests as you can, but be aware that no prep company is even close to simulating the GMAT and its questions

The official resources are limited and thus invaluable.
3. SummaryIt was a long journey and I am very thankful to this community, even though I was a silent lurker during my prep. Don't stress and work really, really hard and you will easily score 700+ on the GMAT. Put in the work, it really is that simple in the end. If you have any questions, I will try to answer.
