Hello friends this is vishav I am writing this after 1 month of detail exploration on this site and on lectures ..today I was studying St. Steel lectures. The way sir taught was incredible ..the thing I loved most is models and animations and pictures the sir used to attach in between ..I am 100% satisfied ..I request all civil engineer graduate students if you wanna learn remember learn and not cram civil engineer then give this thing a try ..remember I am nowhere related to satish sir ,I am just a student ..
