Thank you, TC, genuinely and sincerely. I have learned a lot of different skills to tackle different question types and that I could use them in my tests. My chem grades at least happened to improve after studying these courses. He is a very exam-oriented person who always focuses on main points in DSE and would include them in the topic challenge everytime in order to ensure us that we were familiar with them. It was so much help for me and I believe that his couse can enhance my grades in the future as well! I am absolutely ready to enroll for his upcoming courses!!
