I am pursuing MBA in pharmaceutical management from NIPER Hyderabad with a strong academic record and proven success in national-level pharmacy entrance exams. I secured AIR 61 in NIPER 2024 (MS/M.Pharm) and AIR 27 in NIPER MBA, along with AIR 147 in GPAT 2024 and AIR 907 in GPAT 2023. I also achieved AIR 6 in AIIMS CRE-2025 for Drug Store Keeper and was selected as a Pharmacist (AIR 61) for ESIC. Additionally, I was the Runner-Up in Round 2 of the EY Case Study Competition.
