How to go to MGR college of arts and science from Tnagar.?

I have a exam in the MGR college for arts and science.

I have found the route from tnagar since i am residing there.

Take the bus that Tnagar to Mylapore.

Get down @ satyam studio busstop.

The college will be opposite to the busstop.

Another important thing is that Greenways road MRTS station.

So we can easily go via train but we have to walk for a 600 meters.
