Hello,
As you have not taken biology in your class 12, you can pursue diploma in Nursing by opting for ANM(Auxiliary Nursing and Midwifery) which is a 2 years course and GNM(General Nursing and Midwifery) which is a 3.5 years course.

ANM teaches  how to take care of equipment, setting up of Operation Theater, provide medication timely to patient and maintain records.

GNM deals with the education of nurses in general health care, nursing, and midwifery.

The minimum eligibility criteria is that the students must have passed class 12 th with minimum 45% marks.

Some of the college offering this courses are

• SRM University
• Mahatma jyoti Rao phule University
• Venkateshwara nursing college
• Singhania University

Hope it helps
