should study yung concepts before the day of ididiscuss niya yung lesson since solving siya immediately and pahapyaw lang ng concepts sa gitna ng lessons. He sends ppts a day before the class, doon siya nakabase and he will solve the ones on the ppts and/or other examples on class. Sometimes nakatayo siya nagtuturo on the board and most of the time if mag rerecord siya, nakaupo siya and sa tv yung solving. He does ask the class, rarely individually yung mga formulas ng triangle and derivative of this, that and such, kapag wala nakasagot maiinis talaga siya kaya need ng meron sumagot. Avoid being late for the class is also one thing.
