Hey aspirant,

First of all you need to score minimum 50 % marks in 12th grade (General category) or 40%  marks (SC/ST/OBC) and complete your 12th with Physics, Chemistry and Biology as main subjects along with English. This is the basic eligibility criteria for NEET UG entrance examination.

By giving NEET UG if you secure good rank you can pursue MBBS from any of the good goverment colleges.

After 5 years of completion of MBBS degree you can sit for NEET PG for specialization. You have to rank really well for getting a seat for Gynaecology.

Keep in mind that both NEET UG and NEET PG are national level competitive exams and are way more difficult than 12th board exams. You need to practice for months for ranking well in NEET UG, and you might have to practice for years to rank well in NEET PG.

Hope this helpa,

All the best!
