Hi Student,
MU OET just changed it's marking scheme this year. 
So it's difficult to predict ranks manually with very less information.

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.

Best of luck!
Thank you :)
