HELLO,

Yes if you have passed class 12th from a recognized Chhattisgarh (CG) open school then you will be eligible to apply for GNM ( General Nursing and Midwifery) courses.

GNM is a diploma program for nursing and midwifery . To be eligible you generally need to be atleast 17 years old and have passed your class12th with a minimum percentage often 40% in any stream including English, from a recognized board .

While science background is not always mandatory a science background ( Physics,Chemistry, Biology) can be preferable for some GNM programs

Hope that Helps!
