Huge doubt...

I have this huge doubt- about he 6 weeks residential programme of ICAI.

Has anyone taken it? Is it better than 15 days GMCS?

My friend said the population of girls..is very low... now that's a concern area for my parents.

Plus, how are the amenities there?

Since I know not a single  person who's undergone the residential programme I dunno what to chose!

Please help.. :)
