Hi Deivankumar, my first degree is in Decision Science, which also known as Operation Research. Well I believe you do have the basic mathematics and statistics knowledge which are required as you are from Engineering. Other than that you might need to have some knowledge on basic programming and a strong heart to be able to complete this course 😂
I heard that USM are now try to take new intakes for Master in Data Science which have technical background, others may need to undergo interview to be enrolled. So you may need to contact the school to see if you are qualified to register for this course, or you can try other university which do not have such enquiry. 😊
All the best in your journey!
