Which course is valuable at present.?Please guide me to select the Group in 11th Std.

i would say don't go with the course which is valuable at the moment, reason one everything can change in 3 or 4 years time. what i would really say is that take the time to understand who you're and what you're. take the time to ask your seniors, parents, friends questions regarding the subjects go to the seminars visit the exhibition on education grab as much information as possible
once you have done that you're inner instinct is gonna tell you what to choose and follow you're heart and money will be a sidekick.
