These videos are here to support you to become more independent and confident in your Mathematical journey. Each video starts with hints on how to solve the problem and then asks you to pause and solve it before restarting to check your solution.
Under exam conditions, no teachers or friends can discuss ideas with you before beginning a solution. What questions do you need to ask yourself? How do you take the first step?
