You've worked incredibly hard to reach Silver 1 and 2. To be honest, as the difficulty of the problems increases at the Gold level, the explanations tend to become longer and more complex. Because of this, I am currently debating whether I can deliver the content effectively and if it would be fundamentally beneficial to create Gold-level lectures. I will carefully consider your feedback, including the addition of more Silver problems, and try to move forward with it once I have the capacity in the future. Have a great day!
