I am a member of IEEE society. As i am a student of electrical engineering badge 17 but beside of this i am also a tutor in unique academy. 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. Later on i got scholarship in Punjab Group of Colleges. I got 2nd position in robotics competition in 2018 as my project home automation select for the exhibition in Expocentre.
