Hello Mrudita

The cutoff for admission in AFMC goes 550+ every year. It was 570 NEET score for girls in 2018. And this year, the cutoff is expected to increase by 10-15 marks. And so with a score of 298, you cannot get admission in this college. A minimum of 550+ is required to get a seat in AFMC.
Well, you can try for some private medical Institutes in your domicile state. As you're a reserved category candidate, you may get a seat in govt college but that depends on the previous years cutoff of that particular college in state mainly. The chances are extremely less. And thus you can go for the private colleges option.
You can use the college predictor tool to know about your chances of getting a seat under your state quota:
