We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:

If we take the prime factorization of n we get: 2, 2, p (p is in the prime factorization since were told it is a prime number in the question)

Looking for positive even divisors, we have: 2 4 (because of 2*2) 2n (because of 2 * n) 4n (because of 2 * 2 * n)

The even divisors here are 2, 4, 2p and 4p (not '2n' and '4n').
