i got 400 in manipal what rank i may get

Hi Phani,
MU OET just changed it's marking scheme this year.
So it's difficult to predict ranks manually.

Careers360 is working to fix the Rank predictor to work for MU OET 2019.

4th of May is the estimated date of result declaration.
It's just a few days away.

So you can better wait for the actual result as other sources are not trustworthy due to the change in Exam pattern.
Hope this helps..
Best of luck!
Thank you :)

Kindly visit the link that has been shared below to check last year's closing rank and predict your chances of getting the a seat in the campus of your choice and the course you wish to pursue:

However, this year as we know the pattern has changed and the total marks has been increased to 800 so you will only get to know the exact position and status once the results are published since we do not have any past year data to refer to.
