Below are links to instructional videos that are freely available to those students who sign up with Daniel’s Maths Tuition NZ for at least a term. They range from basic NCEA Levels 1-3 material up to the final year of university, and cover the fundamentals of maths/physics in a systematic way. They are not a substitute for your school or university course but complement the material you are learning, in tandem with our private tuition.
