To pursue MBBS, NEET is the only national level examination that you can give. Other entrance examinations are for various other medical courses which can be conducted at national level (such as AIAPGET, FGMB, DNB for post-grad courses). or at Institute Level (such as JPIMER PG, AIIMS SS, NIMHANS etc.)
No, I am extremely sorry to tell you dear but there's no entrance exam other than neet if you want to do MBBS.
This is because,
NEET is the single and the only gateway to get admission in all the medical colleges for MBBS and BDS and it is also accepted for ayush courses like BAMS, BHMS etc, Veterinary i. e BVSc.
Without Neet examination , you can not get admission in any medical college be it government or private , not even under management quota in private medical college
Leave India you cannot get admission in even abroad without Neet examination, as Neet is compulsory to qualify even for admission in abroad for medical or Dental College
I suggest you to prepare well for neet examination so that you can qualify it and get admission in medical college for your mbbs ,first of all go well through NCERT and master it , make routine or timetable and religiously follow it , it should revolve around study, practice and revision .After finishing each chapter you should practice questions of the same chapter and once you are done with complete syllabus, go through NEET mock test papers .
