JEE Main 2019: Rise in Number of Female Aspirants for January Session

JEE Main 2019 is all set to be conducted from January 06 to January 20 in online mode. JEE Main Registration for January session closed on September 30, 2018 and the numbers are slightly surprising. The number of applicants has dipped to 9.65 lakhs as compared to 11.5 lakhs last year. However, there is a positive rise in number of female applicants in JEE Mains this year.

Last year JEE Main saw 10.4 Lakh candidates appear in the exam. Only 24% among these candidates were female. The dip in number of overall registrations can be attributed to the fact that exam will be conducted twice this year and many aspirants are still in the final phase of preparation. Also the overlapping between JEE Main and Class 12 Board Practical exams is another decisive factor.

More applications are expected in the second session of JEE Main in April. But the rise in number of female applicants is a positive reaction for the Government and officials.


Complete Guide to CBT Mode for JEE Main 2019

JEE Main Exam will completely shift to online mode after the National Testing Agency or NTA takes control of the management of the exam. However, until 2018, a vast majority of the aspirants have opted for the pen and paper test, that is the offline mode. In 2018, the Central Board of Secondary Education or CBSE conducted the test for the last time.

Under the supervision of CBSE, JEE Main was conducted in both the online and the offline mode and according to the trends, the greater portion of the students went for the offline mode of the exam or the pen and paper based test.

However, in recent years, a discernible increase has been noticed in the number of students opting for the online mode of the exam. Here is comprehensive guide on JEE Main CBT mode for students who will for the first time in January 2019 session.

Confusions and fears among the students regarding the CBT

Usually, there remains a general confusion about the nature of the online mode of the exam. Many consider it to be an internet-based exam, which is, in reality, not the case. The online mode of the exam is a Computer-Based Test or CBT that only has the need for a Local Area Network (LAN). The exam is not dependent on the Internet connection and the LAN is used only to make sure that the whole examination process is executed with ultimate safety and without any intrusion of glitches.

  • There might be power failures or technical glitches in the exam centers
  • The responses given by the examinees may not be recorded properly etc.

The reality

In response to all the concerns listed above, it can be said that CBSE has been conducting the JEE Main Exam in the online mode since 2014 and no such problems have been reported yet. Regarding the difficulty in handling the computer, it can be said that no special training is required to appear for any CBT, only the basic knowledge of handling the mouse is sufficient. These things have been clearly declared by CBSE when they previously published the FAQs on the online mode of the exam.

Practice sessions that can help

This time, NTA has taken a helpful step with the intention of making things clearer. In order to provide the students from the rural areas the chance to get familiar with the essentials of JEE Main CBT mode, NTA is going to establish free practice centers.

3000 training centers are stipulated for the purpose of training aspirants from rural areas and remote locations for the CBT. Students having the internet facility at their homes can also download these practice test series questions and get themselves prepared likewise.

Advantages of the CBT

  • No special computer knowledge is required except for knowing how to handle the mouse
  • Chances are there to review and change a given response
  • No threat of a leak
  • An automatically set clock at the screen that shows the time left, the number of questions answered, the number of questions left, and the number of questions left for review
  • Results are expected to be declared much earlier

Disadvantages of the CBT

Apart from the general fear of appearing in the CBT among the rural candidates, there is no big disadvantage expected from the CBT. However, both the NTA and the MHRD have taken this matter into special consideration and that is why the practice centers are going to be operated soon from the ending of this month.

So, the aspirants are advised not to believe in the rumors and myths. They need to get prepared for the examination at the right time and make use of the opportunities offered.
