Hello aspirant,

Firstly,your question lacks the exact details...There are lot of colleges in this name in coimbatore . Don't fall a victim to any rumours .There is no proof on their college websites that they offer complete free seat.Incase of providing free seats,they mention it anywhere know,kindly ask the students studying  there still the present and confirm whether it is trustworthy.Decide only after complete enquiry . Here ,I am attaching the link of the college which I searched by the name you mentioned.
