Hii

For the purpose of jb, your schooling does not make much difference, its you highest degree and its college which is taken into consideration.
Talking about open schooling, Its is valid in India and has been approved by Education department of the govt of india. SO ofcourse open schooling is valid every where. May that be job or any higher education.
For job what actually matters is if you have all the required skills and degree which the company expect from its employee. 
SO you schooling was done from a govt school , a private school or open schooling does not make difference all you need to focus on is to improve the skills required for a particular job.
The higher the degreee and skills, more is the chance of employement and higher salary.

Hope this helps
Thanks!!
