Months passed and soon came the end of the second trimester. Lith's teaching methods gave Marth a headache, but it was the good kind. Unlike other Professors, Lith wouldn't leave everything to self study and give only cryptic advice.
Lith always gave a full explanation of the exercises he assigned and even a short tutorial. The problem was that none of his lessons were simple. The exercises always required a deep understanding of the principles of advanced magic and the ability to put them into practice.
It resulted in half the class acing the exercises and the other half failing miserably. Oddly enough, the results seemed to be influenced more by each student's amount of practice rather than by raw talent.
The reason why Marth hadn't ordered him to use more orthodox methods was that those who thrived in Lith's lessons would also improve in most of the other subjects.
