Before introducing the IBPS exam , so many students taken the exams of SBI PO, CANARA BANK,ANDHRA BANK exams, which are very similar to IBPS, but did not got success. the reason behind, you are not following properly 3 things. Let me explain one by one
1) All topics not covering
If you did not cover all topics in any sections, results you fail in exam. At least you have to cover basics of the topic, if you know the basics, which are enough to solve the problems. When ever you will qualify in all sections, then only its possible to get the job, so don’t neglect any topic, minimum know the basics of the topic.
2) Concentrating only on some topics/sections
Its clear that you have to qualify in all sections in IBPS exam, so for din’t concentrate particularly on one topic/section, you must have the basic knowledge of each topic/section
