Hii,

Even with 33 percentile in PCB, there are still a number of health and allied science courses you can explore other than nursing. Nursing is a great field, but if you want alternatives, here are some:

• BMLT you can  work in diagnostic labs, hospitals.
• Bachelor in Physiotherapy (BPT): Focus on physical therapy and rehab.
• B.Sc. Radiology / Imaging Technology: Deals with X-rays, MRI, etc.
• Bachelor in Optometry: Eye care and vision testing.
• B.Sc. Nutrition & Dietetics: Focuses on diet and wellness.

Many of these courses are available in paramedical colleges, and admission is either direct or based on state-level entrance exams. You may not get into top institutes with 33 percentile, but private or mid-tier colleges do offer seats, and the future scope is promising if you're passionate.

Thank you and all the best!
