M.Math is quite thorough in different ways, it is best not to end up opting for it without vital information. As a brief interpretation, you really do not require programming skills to further opt for the M.Math course. 

• A very intensive knowledge of linear algebra, real analysis, and basic abstract algebra is required prior to joining the M.Math course. Despite that, the course is very challenging. 
• The academic background does not necessarily affect the course you are about to take up. There are students who arrive from an engineering background. 
• It is best to go through the coursework of Mathematics and decide whether or not you are inclined towards it or not. 

M.Math students usually secure placements at a variety of companies, but achieving that howsoever is extremely difficult. Thus, choose only if you are confident.
