No, as a computer science student, you wouldn't be at an advantage attempting the GATE exam in Mechanical Engineering (ME) with your current background, because:

1. The GATE ME syllabus covers a wide range of mechanical engineering topics like Engineering Mechanics, Thermodynamics, Fluid Mechanics, Machine Design, Manufacturing Science, and more. These subjects require a strong foundation in mechanical engineering concepts.

2. The GATE exam is known for its depth and difficulty. Without a strong foundation in mechanical engineering principles, attempting the ME paper would be very challenging.

I hope this information helps you.
