Dear Aspirant,

As per the trend that is seen every year in NEET UG, there is certainly not even a percentage possibility for the cutoff to reduce even till 450. 300 -350 is way too less, 

On the contrary, the cutoff is increasing every year by 20-30. Even 500 cannot be considered as a perfect marks for the cutoff, as it used to be few years back.

The only way to get into a medical college now is practice and hard work. Solve 3-4 previous years question papers everyday till Saturday. Be thorough with Biology NCERT of class 11th and 12th. Still not too late.

All the best! Do well! :)

You can't be reducing the cut-off, it's the institutions who decide the cut-off and not the candidates. Now, you can't be getting into a government medical college with this score if you belong to the unreserved category, but you can get into private colleges if you can and if you want to.
