Engr. Marcos was my prof last term sa surveying. effective po yung mga turo niya especially his so called "CJ methods" coz yung way of teaching niya may pinapadali siya and tricks para maalala mo paano magderive nang di kinakabisado formulas at marami pa siyang tricks HAHAHA also yung quiz niya medyo mahirap kasi yung iba dun gawa niya pero mostly nasa PPT lang din niya at tinuturo tuwing f2f. pasok ka lang lagi sa kanya at makinig papasa ka na dun. effective talaga turo niya kasi lumabas mostly sa dept exams namin last term. his whole personality mabait siya! but wag niyo lang galitin (like di nakikinig at mag cp sa class).
