Graduate Pharmacy Aptitude Test (GPAT): Microbiology Syllabus

The Graduate Pharmacy Aptitude Test (GPAT), opens doors to infinite opportunities for students from pharmaceutical domain. GPAT is a National level entrance exam for admission into prestigious NIPERs and University colleges. Since 2009, the importance of GPAT has increased as the branch turned into a autonomous exam and separated from GATE (PY). The exam will be conducted by National Testing Agency (NTA) from 2019, previously by AICTE under the guidance of MHRD, India.

Syllabus prescribed by NTA for GPAT includes MICROBIOLOGY is a minor subject with topics that are elaborated below.
