The three things that brings success to most candidates in PSC Exam is a triad of selection, planning and learning. All the three limbs are equally important.
A good selection of topics, effective time management and actual learning itself are all key in PSC exam success. It is important to know which topics to cover in the first instance. There is a hierarchy for selection that toppers follow. The most common and repeated topics should be covered before any new areas are explored. Most people try and grab new topics when their basics are weak. This is a fatal mistake. On the other hand when you get the most common question wrong, it puts you behind some 5000 people!
Planning and time management is very personal and cannot be generalised. Finally, the hardest bit – Learning. It takes effort and consistency in sticking to your objective for effective PSC exam preparation.
