NEET and JEE Main to be conducted twice a year by NTA instead of CBSE

NEET

- No comments

The Center is considering to conduct the Entrance tests (NEET, JEE Main) for admissions to undergraduate courses in medical and engineering twice a year from 2019.

The government is in the process of setting up a National Testing Agency (NTA) which may start its operations from 2019. The agency will take over all the entrance tests now conducted by CBSE (Central Board of Secondary Education). These entrance tests are NEET (National Eligibility cum Entrance Test) for MBBS admission, the JEE Main (Joint Entrance Examination Main) for B.Tech courses and the NET (National Eligibility Test) for selecting teachers eligible to be appointed in colleges and universities.

"The NTA (National Testing Agency) will initially conduct those entrance examinations which are currently being conducted by the CBSE ... Other examinations, tests will be taken up gradually after the NTA is fully geared up ... The entrance examinations will be conducted in online mode at least twice a year, giving adequate opportunity to candidates to bring out their best," HRD Minister of State Upendra Kushwaha said in a written answer in the Lok Sabha.

At present all these entrance tests NEET, JEE Main, NET etc. are held once in a year. If the proposal is passed, then from 2019 National Eligibility cum Entrance Test (NEET) and Joint entrance Examination Main (JEE Main) will be conducted twice a year by NTA instead of Central Board of Secondary Education (CBSE). NTA will also locate the examination centers at sub-district and district levels.

Answer 11: (c).

Answer 12: (b) Hint: Hydrogen at the moment of formation is known as Nascent Hydrogen. It is believed that part of energy liberated in the reaction producing hydrogen become associated with hydrogen molecules and thus, make them hyperactive.

Answer 13: (b) Hint: Two OH bonds lie in the different planes.

Answer 14: (c) Hint: Repeated electrolysis of 3% aqueous solution of NaOH.

Answer 15: (d). Answer 16: (b). Answer 17: (c).

Answer 18: (c) Hint: A solution of K₂Cr₂O₇ in H₂SO₄ is oxidised to blue chromic acid by H₂O₂ and dissolve in ether to give blue coloured solution.

K₂Cr₂O₇ + H₂SO₄ → K₂SO₄ + H₂Cr₂O₇
