Hello aspirant,
The competition for medical seats, especially in private colleges, is extremely intense. Cutoff marks have been rising steadily over the years. To get a seat in a private medical college, you would generally need a score significantly higher than 425.
But, you should not lose hope here, instead, you can consider other healthcare-related fields like BDS, BAMS, BHMS, or paramedical courses. If you're determined to pursue MBBS, focus on improving your score for the next NEET exam.
Remember, it's essential to stay positive and explore alternative paths.

I hope this information helps you.
