NEET Eligibility: Are Private and NIOS Candidates eligible to appear in NEET exam conducted by NTA ?

- No comments


Doubts and Questions regarding Eligibility for NEET (UG) Exam

Can a private candidate give NEET (National Eligibility Cum Entrance Test - UG) ?

Are private candidates eligible to appear in NEET exam conducted by NTA ?

Does private candidates appear in the NEET Exam ?

Are the NIOS candidates passed 10+2 from Open School eligible for NEET ?


Till today Candidates who have passed 10+2 from Open School or as private candidates shall not be eligible to appear for ‘National Eligibility Cum Entrance Test’. To be eligible to appear in NEET You should have studied for a continuous period of two years as a regular student, studying Physics, Chemistry, Biology/Bio-technology at 10+2 level.

However, this matter is lying before the Hon’ble High Court of Delhi, Hon’ble High Court of Allahabad, Lucknow Bench and Hon’ble High Court of Madhya Pradesh at Jabalpur. The provisions of the regulations disqualifying recognized Open School Board candidates and the candidates who have studied Biology/Biotechnology as an additional Subject has been struck down. Keeping in view of this, candidates who have passed 10+2 level with Biology as an additional subject will also be eligible for MBBS Entrance Examination (as per Hon’ble High Court Order No. 2341/-W/DHC/WRIT/D-1/2019 dated 24/09/2019 in the Writ Petition (C) No. 6773/2019).

The Medical Council of India (MCI) has preferred Special Leave Petitions before the Hon’ble Supreme Court and Appeals in the Hon’ble High Courts. Therefore, the candidature of candidates in the NEET (UG)-2020 who have passed the qualifying examinations i.e. 10+2 from National Institute of Open Schooling or State Open Schools or as private candidates from recognized State Boards; or with Biology/Biotechnology as additional subject shall be allowed but subject to the outcome of Special Leave Petitions/Appeals filed by the Medical Council of India).

Further, CBSE candidates who have opted for Biology as an additional subject, private candidates, and distant learning candidates, all these candidates are eligible for NEET and hence, can appear in the NEET Exam (National Eligibility Cum Entrance Test - UG), which is conducted by NTA, like a regular candidate. He/she should have 50% marks in your intermediate as an unreserved candidate and 45% for reserved candidates (OBC/SC/ST).

The new National Education Policy 2020 (NEP 2020) at a glance

- No comments


National Education Policy 2020 (NEP 2020) - A Brief Outline

The National Education Policy 2020 (NEP 2020), a draft of which was approved by the Union Cabinet of India on 29 July 2020, replaces the National Policy on Education of 1986.

EduNews @

The new National Education Policy 2020 (NEP 2020) outlines the vision of India's new education system. The new policy replaces the previous National Policy on Education, 1986. The NEP 2020 envisages transforming India's education system by 2030.

The Policy envisages a new curricular and pedagogical structure for school education that is responsive and relevant to the needs and interests of learners at different stages of their development. National Education Policy 2020 aims to shape an education system that benefits all of India's children. Prime Minister Shri Narendra Modi is hopeful that the new NEP 2020 will increase thirst for knowledge in schools and help in removing pressure on mark sheets for students.

Why National Education Policy

Policies are important because they help a school establish rules and procedures and create standards of quality for learning and safety, as well as expectations and accountability. Without these, schools, colleges, universities would lack the structure and academic guideline. The National Education Policy would help to function and provide the necessary educational needs of students.

For the first time the Government of India framed a National Policy on Education in 1986 which was later modified in 1992. Its major objective was to provide education to all sections of society, with a particular focus on scheduled castes, scheduled tribes, other backward classes and women, who were deprived of educational opportunities for centuries.

Changes in the new National Education Policy 2020 (NEP 2020)

Education Policy in India has been changed after a long period of 34 years. According to the National Education Policy 2020, Govt will phase out the affiliation of colleges in 15 years and a stage-wise mechanism will be established for granting graded autonomy to colleges. Under NEP 2020, there will be no rigid separations between arts and sciences, between curricular and extra-curricular activities, between vocational and academic streams.

The remarkable things about the New Education Policy 2020 are as follows:


1. Nursery at 4 Years Old.

2. Junior KG at 5 Years Old.

3. Senior KG at 6 Years Old.

4. Class 1 at 7 Years Old.

5. Class 2 at 8 Years Old.


6. Class 3 at 9 Years Old.

7. Class 4 at 10 Years Old.

8. Class 5 at 11 Years Old.


9. Class 6 at 12 Years Old.

10. Class 7 at 13 Years Old.

11. Class 8 at 14 Years Old.


12. Class 9 at 15 Years Old.

13. Class 10 at 16 Years Old.

14. Class 11 at 17 Years Old.

15. Class 12 at 18 Years Old.


  • There will be Board Exam in Class 12 only. Whereas earlier, it was mandatory to take Board Exams in Class 10, which will not happen now.
  • 4 Years of College Degree.
  • No more Class 10 Board Exam.
  • M.Phil Degree will be abolished.
  • Now students up to Class 5 will be taught in Mother Tongue, Local Language and National Language only. The rest of the subjects, even if they are English, will be taught as a subject.
  • Examinations will be done in the Semester form from Class 9 to 12 standard.
  • Schooling will be done under the 5 + 3 + 3 + 4 formula. (see table above).
  • College Degree will be of 3 and 4 years course.
  • Certificate will be given on the First year of Graduation, Diploma on the Second year and Degree in the Third year.
  • 3 Years Degree is for those students who do not have to take Higher Education. At the same time, students doing Higher Education will have to pursue 4 Years Degree.
  • Students pursuing 4 Years Degree will be able to do Master's Degree in one year. 
  • Now, students will not have to pursue M.Phil rather, MA students will now be able to pursue PhD directly.
  • Students will be able to do other courses in between.
  • Same rules will be applicable for all Government, Private and Deemed Institutions.


Gross enrollment ratio will be 50 percent by 2035 in Higher Education. At the same time, under the new Education Policy Rule 2020, if a student wants to pursue another course in the middle of a course, then, he/she can take a second course by taking a break for a limited time from the first course.

Many reforms have also been made in the Higher Education. Improvements include graded academic, administrative and financial autonomy etc.

Apart from this, the new National Education Policy Rule 2020 (NEP 2020) has recommended for e-courses to be started in Regional Languages. Virtual Laboratory will be developed. A National Educational Scientific Forum (NESF) will be started.
