Most of my career as programmer spend developing programs using PHP and MySQL. In this article I would like to share my program that I wrote a long time ago I called this program Student Grading System in PHP and MySQL. This program will compute and store the grades of the student in MySQL.
People here in the Philippines can reach me at my mobile number 09173084360.
Thank you very much and Happy Programming.
