One of the best lecturers I 've met so far . Love to work with him . If we attend the lectures there is no need to work very hard to study because of the ability of Ellen sir to teach and guide us . The best lecturer I met in the university so far . One of the few lecturers that have the passion and dedication to teach the students.But little too strict when marking papers , So please be kind enough to , not reduce marks for simple mistakes that we have done in the exams . As human beings mistakes happen , and they happen not intentionally . We normally try to reduce that as much as possible but with pressure we face , mistakes happen . So please consider about this . What ever your decision about this matter , as I said earlier you are the best , and we were fortunate enough to learn from you !
