Kingsley taught us the MCQ and SQ skills, which are unbelievable and unpredictable. The main reason I join this course is that the course teaches us three 5** must-know topics (3D Trigo, four-centre and circle equations). And then the future paper mixes up these three topics to be a killer question in the DSE, which is very powerful for us to ace the Maths (Core) DSE exam.
