Just gave exam yesterday(16 May 2018) got 610(Q47 V27) 
I have been studing for around 9 months and getting good scores in mocks but not in real paper .
Please give me any suggestion or solution as i am in desperate need of it.
 
I am not able to figure out why i am performing so bad on real test.
I am not able to sleep well before exam(have anxiety) but it should not reduce my score so much.
In desperate need of help??
Please i am ready to study again and even ready to do anything to get atleast 700+ on real test.

Need advice for future preparation and how to get a real image of my ability.

Hi swastik3,

I'm sorry to hear that Test Day didn't go as well as planned. When these types of score drops occur, the two likely "causes" involve either something that was unrealistic during practice or something that was surprising (or not accounted for) on Test Day. If you can answer a few questions, then we should be able to figure this out:

When you took your CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as when you took your Official GMAT?
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)? 
5) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE (re: on a prior CAT, in an online forum or in a practice set)?

Answers to your questions

I did not take an official test before this attempt as i was previously scoring in high 750+ in them.
So went for veritas tests as i believe they are quite good and new for me.
Veritas prep-1 28 April 760 All except AWA order Q V IR AWA different time donot remember exactly
Veritas prep-2 6 May 730 All except AWA and IR order Q V IR AWA
Veritas prep-3 8 May 730 All except AWA and IR order Q V IR AWA
Veritas prep-4 10 May 740 All except AWA and IR order Q V IR AWA
Veritas prep-5 11 May--in evening 720 All except AWA order Q V IR AWA
Veritas prep-6 12 May 760-- a little long break for verbal section as was not feeling well All except AWA order Q V IR AWA
Veritas prep-7 13 May 790 All except AWA order Q V IR AWA
1- I did take my veritas prep(all 6 test) very recently and did not take IR(for first 4) and AWA(for all) but i did score 8 on IR on real test(latest one) .
2- Yes i did take them at home in comfortable environment.
3- 4-at same time(12:30) and 2 -at different time
4-may be once or twice due to some reasons such as internet connection ,
5-No veritas were new ones that i just bought to pace myself for real one

Thanks again for all the help.

Hi swastik3,

From your prior post, there were some 'red flags' in terms of how you took your CATs. Before we discuss those issues though, I have a few additional questions about the lead-up to Test Day and Test Day itself:

1) What did you do in the 3 days before your GMAT?
2) How did you sleep the night before your Test?
3) How long was the ride to the Test Center from your home?
4) Were there any distractions at the facility or during the Test?
5) What did you do during the two 8-minute breaks?
6) Did you finish any sections early?
7) Did you have to rush to finish any sections (and guess on questions just to finish on time)?

1-Took 2 veritas official papers on 13 and 14 may 2018
and rested on 15(revised notes i have for verbal and quant) and tried to relax as much as i could.
2-no not great at all .i slept in bits and pieces and was not feeling good in morning but still went with it(did not have breakfast as i was not feeling well in the morning). I agree that i have anxiety but it should not bring my ability so much down(around 150 points)
3-30 to 40 mins
4-mostly was feeling very disappointed but was trying to get myself going.I did drink water but have never eaten any thing in these breaks even in mocks.
5-no i am struggling in both the sections quant and verbal and nothing was going well(had to guess 4-5 question in quant and 5-6 last ones in verbal)
6-no none.
7-quant has always been strong area(got Q50(last attempt) and got Q51(all the mocks))so this time started but i believe after 10 mins into exam i knew it was not going well but after quant i decided to give my best in verbal as i was mainly looking for improvement in it but it also went badly.
I had to rush in both to complete. In quant in between question and in verbal last 6-7 question which had 1 RC)
