Hi Aditya,

According to the updates, there are no specific marks requirements mentioned for either class 10th, 12th or your Graduation degree. However, a minimum of 50% aggregate marks with a recognised Bachelors Degree is always more advisable. 

The main eligibility criteria for the candidate is to secure more than 50% in the qualifying exam and a Bachelor's Degree of minimum 3 years tenure, in any discipline from a recognised University. There is no age limit for the candidate and even students who are in their final year of graduation can also apply for the exam. 

I hope this helps your out. Please follow up for any further help or query that you may have. All the best!
