When preparing for the test, the most common slipup is forgetting to block some time for learning.

Postponement and pretexts are your biggest enemies. Please adopt a learning schedule and stick to it.

The second common mistake that leads to failing the real test is the fact that students spend too much time on one question and end up not making it through the whole test.
