The cutoff as usually been around 451 to 465 for males and females separately over the last few years and so you should be trying to score in excess of that requisite amount to make your chances clear for subsequent round selection
I don't think so because according to the guidelines given in official website once you clear NEET exam successfully you'll have to register yourself on the medical counselling committee website.
In which you'll find a subhead Afmc Medical counselling where you need to register.
Once the registration is done and the results are out the shortlisted students would be called for screening tests.
Hope this helps
All the best.
