GLA university is better than PSIT Kanpur. One of my relatives is doing her B pharm from there. According to her, the placements are very good there. It not only provides good placements but there is a lot more than just this.
The table below shows a brief overview of the colleges:
Bharat Serums and Vaccines, Cadila.
Cryobank International, Ipca Laboratories, Ranbaxy.
Placements for the last few years of B Pharm have gone very well. Students have got very good career opportunities and jobs. To conclude, GLA mathura is better than PSIT kanpur.
