Active recall and rewriting have been the most effective learning strategies for me. It has helped me reinforce my understanding and increase my memory of challenging subjects. Ive found that when I break down large topics and actively test myself, I engage with the material deeper than when I am just reading it. This not only helps with the main exam that I am preparing for but also cumulative exams in the future as it builds long-term memory. Response to this.

A possible CodeRunner question of the type "Write a function" could be the following. Write a function calc(num) which tests if a given positive number num is a prime number or not. If it is a prime number, the function must return the value 0. If it is not a prime number, the function must return 1. Your code is automatically checked with several test cases. Two of them are listed here with the expected result. For example: Test Result a = calc(5) print(a) 0 a = calc(8) print(a) 1 Answer: (penalty regime: 0%)

3. The quantum virial theorem states that in a stationary state $0 = 2 \left< \frac{\hat{\mathbf{p}}^2}{2m} \right> - \langle \hat{\mathbf{r}} \cdot \nabla V \rangle$. Use this to determine the expectation values of the kinetic and potential energies of a hydrogen atom in a stationary state with principal quantum number $n$ and energy $E_n = -\frac{e^2}{8\pi \epsilon_0 a_0 n^2}$.
