Help to correct my text about pharmaceutical

The owner of the place stayed and monitored me all the time, he supervised me, he gave me tips, taught me and rid my doubts about medicine and the dangers of pharmaceuticals. He also furthered my knowledge  about writing prescriptions; it made me endeepen my knowledge that I got from my university. The goal of this internship was to add to the knowledge I received in university with the day to day work schedule in a pharmacy. It’ve(this is not a word) been teached and evaluate right way per a pharmaceutical and It made me better understand the importance of the pharmaceutical industry because it is heavily present in our lives. In addition, its effects offer safe and competent results on the works doing to the user,  but pharmacists make sure the results are correct and effective. I learned new tasks such as: how to do a blood glucose test, pressure calibration, give injections, and deliver medicine. It was always with the accompaniment of the pharmaceutical owner as well.

good job..... the pharmaceutical industry is a hard topic to write about. The paragraph was confusing to read, but I tried to correct it as much as possible. Good luck with your studies and learning English!
