Hello Aspirant,

Minimum criteria to apply for IAS is graduation from any stream so after 12th you cant apply for IAS exams.

You can go with MBBS preparation first because that is important for your career now.IAS and MBBS both needs more time to study so you cant go with both on the same time as it will create problem and both have different syllabus so it create a confusion  for you .Its better you should first go with MBBS First and then if you think you are capable and can get hard for IAS then try in Last year.
