| Re: UGC NET Exam for Electronics eligibility
The UGC NET Exam is conducted to determine eligibility for college & university level lectureship and for award of Junior Research Fellowship (JRF) for Indian nationals in order to ensure minimum standards for the entrants in the teaching profession and research.
Eligibility:
The applicant must have secured at least 55% marks (without rounding off) in Master’s Degree OR equivalent examination from universities/institutions recognized by UGC
AGE LIMIT
For Junior Research Fellowship: Not more than 28 years
Lectureship: There is no upper age limit for applying for lectureship eligibility
Electronic Science paper pattern:
There will be two question papers UGC NET Electronics:
Paper II will cover 50 Multiple Choice Questions ( Multiple choice, Matching type, True / False, Assertion-Reasoning type ) carrying 100 marks and UGC NET Electronics
Paper III will have two Parts-A and B.
Part-A
This will have 10 short essay-type questions ( 300 words ) carrying 16 marks each. There will be one question from each unit with internal choice from the same unit. Total marks will be 160.
Part-B will be compulsory and questions will be set from Unit-I to Unit-X. The candidate will attempt only one question from Part-B ( 800 words ) carrying 40 marks. Total marks of UGC NET Electronics Paper III will be 200.
