I teach calculus, communication skills, mechanics and economics. I am also a home tutor. My student Muhammad Salman Alvi is a brilliant A-level student and he performs very well in academics when i start to teach him. His weak point was mathematics but now he is performing well in mathematics. I am a scholarship holder in Fsc as i scored 1017 marks in metric out of 1100.
