I was opportuned to attend his chemistry class as an undergraduate 100level Engineering Student at SLT (2005). We enjoyed every bit of his course though we were troublesome. Class full of humour and will always flow regardless of the situation. Highly impressed with his energetic presentation which reminds me of his complete energy at SLT between 4pm & 7:30pm which sometimes extends because he never get tired. Prof. Alafara, May Allah crown your effort with more success.Proud of you
