Hello student,
As you are inquiring about the number of students who have secured 450 marks in NEET this year, let me tell you that this data is unavailable, as it cannot be predicted accurately without the colleges cutoffs coming up.
If you go by the 2018 merit list, it can be said that students around 35 to 40 thousand all over India are most likely to get over 450 marks.
Good luck
