Current Events

This part of the exam is quite the trickiest one since anything under the sun could be asked in the question paper under this section. Aspirants must prepare this section by regularly following the newspaper. They should update themselves with the happenings in the country as well as those events happening on world panorama. They may prepare their own notes for such important events; this will enhance their memory and help them during the exam.

Along with the syllabus, you should carefully read the exam pattern. It will help you during the preparation of the exam.
