Gotta say, Leo's learning ability is really good. Elementary school knowledge and a part of middle school stuff was learned clean by him within one session.
About teaching more, Michael couldn't remember more anyway and it wasn't too necessary. After all, the system mentioned is about simple calculation speed, not thinking ability.
The upcoming time is just practicing solving some simple exercises in different question types to increase the diversity in calculation. This is something the two of them deduced during study from diverse practical experiences in combat.

During this period Michael and Leo continuously solved different types of questions, making Raphael see it and get a headache along with them because they did it by mouth and were incredibly noisy. The two rarely had such a long time without fighting like this.
"Time to check the results of the last few days. Ready?"
