-    Hi! I've just finished first year and I have recent experience with the above courses. I'm thorough with the course concepts (having scored 94+ in all these courses), and have learnt how to explain the concepts in an easy-to-understand manner. I also understand exactly how to succeed in the courses' various assessments. I'll do my best to help you improve enjoy the subject, learn, as well as improve your grade!
