i too was interested in this school and managed to get an open seat while in rishikesh and asked if i could visit the school and talk to the students
I turned out to be an multi-level hotel type building in a quite small foot print with a nice yoga shala near the roof.
nothing like the pictures on their website, we were told that was from the old place. no garden, no place to walk on the grounds, (you go out to the public street to stretch your legs with traffic , pilgrims and people)
we talked with a student there who was on her 3 rd week, she said she liked parts of the course especially the philosphy and bagavad gita teacher
the yoga asana classes were okay, not very subtle or adjustment oriented, quite basic
there was no pranayama practiced as a group in the daily schedule
she said she was glad she took the course, she'll have her certificate, and now she knows she has so much more to learn and an idea of what to deepen her knowledge of next.
after that, we canceled, and searched again, and found there is no perfect yoga training course in india, you'll never find everything in one month training
so i say, pick one, do it fully, and get your certificate, then study with a teacher somewhere more personally, either rishikesh, delhi, mysore, bangalore, chennai, etc.
