Hey,

Since you've not mentioned the entrance examination about which you're asking, so as per your assumption, I consider it as NEET UG 2020.

Though the Directorate of Medical Education (DME), Assam till now hasn't declared the official cut-off marks of top and eminent Medical instituion for this year, still if you go through the previous year's (2019) details thoroughly you can get a vivid perception regarding your query, so just have a look in it: https://medicine.careers360.com/articles/neet-cutoff-assam

So after minutely analysing the 2019's informations provided in the above website, I guess it's quite clear for you also that you can definitely get admission in several top Government MBBS and BDS instituions under EWS quota.

MBBS and BDS Instituions as per your expected marks and reserved category:

• Assam Medical College, Dibrugarh
  
• Gauhati Medical College, Guwahati
  
• Govt. Dental College, Silchar
  
• Govt. Dental College, Dibrugarh
  

Moreover your marks and percentile are also perfectly suitable for many renowned private institutions in Assam, if you wish you can go for it.
