Dear Sharanesh,

Both are top courses but vary greatly in their syllabus. Mathematics and Scientific Computing is based on solving practical engineering problems with the help of Scientific Computing. The course is growing in India and has an immense scope both inside and outside. The syllabus is also a bit heavy but interesting. On the other hand, electrical engineering in IIT Madras is an evergreen branch and also has immense scope. It all depends on your interest. So I reccomend you to refer the syllabi sheets for both the courses and take decision.
