This Course has been completely developed and executed by Dr. Rajaa. Dr. Rajaa, is an international academician with over 20 years of experience in teaching the subject in Universities across America and the Caribbean. Dr. Rajaa is also a published author and is currently involved in R&D of statistical models for several international agencies. The course has been made available free of charge to all students and this has been largely possible due to the voluntarily service given by Dr. Rajaa. Learning is best achieved if students could attempt all of the questions again repeatedly.
