I have been teaching students for 5 years now in different subjects and it's truly been one of the most rewarding experiences of my life.
I have also done one-to-one tutoring with 100+ students and help them achieve great subject knowledge.
I have expertise in computer subjects like C++, C, Java, and Python programming and other computer Science related fields.
Many of my student's parents message me that your lessons improved their children's grades and this is the best only thing you want as a teacher. I have done plenty of studying and lots of learning on many exciting and challenging topics. All these experiences have influenced my decision to take on the teaching role in various capacities. As a tutor, I am looking forward to getting to understand your needs and helping you achieve your academic goals. I'm highly flexible and contactable. I am available to work on short notice since I only prefer to work with very small and select groups of students.
