Before contacting Mr. Shafik I tried to look online for many online courses using Coursera and LinkedIn learning and even I’ve watched more than 200 videos online on YouTube Trying to learn the basics of the PLC, it was really hard journey for me, but honestly after I took the courses with Mr. Shafik it was really a game changing for me it was really easy to learn from his courses the way of teaching was amazing, very simple and very systematic you can advance really easy from the basic to advance level
