I am a dedicated tutor with a background in International Business and Marketing from Concordia University. As an honour student, I understand the challenges of academic life and enjoy helping others navigate their studies with confidence. With over a year and a half of experience as a Teaching Assistant in different COMM classes and many years of private tutoring,
I’ve developed a passion for helping students succeed. My goal is to create a supportive and engaging learning environment where students can grasp complex concepts and develop their problem-solving skills. I believe that with the right guidance, anyone can succeed, and I’m excited to be part of that journey at Checkmark Tutorials.
