Dear Aspirant,

As you are expecting 66 marks in SNAP 2019 and after the declaration of result those who clear the cut off will be proceeded for further steps that are Group Exercise (GE) and Writing Ability Test (WAT). The cutoff will be released tentatively in second week of January and then every institution will release its cutoff separately. After analyzing past years cutoff you have the chance to get a seat in SIBM Bangalore, SIIB, SSBF, SIMS, SIIB (Energy / Agriculture), SIHS, SSMS, SSSS, SSMC, SICSR , SIOM, SITM, SCIT, and SIMC but the cutoff for SIBM Pune and SCMHRD Pune goes higher so the chances are less, still there is a chance of miracle to happen.
Kindly check this out - SNAP Cutoff

Hope this is helpful.
Have a great day!
