IBPS PO and clerk is one of the easiest exams but still still students finds it very difficult to succeed. Most of the candidates finds to difficult to manage time and unable to attempt questions which can be solved in no time.
1. Attempt reasoning section at last
Reasoning is the most difficult section of IBPS and other job exams. Cutoff of this section remain low but candidates waste their time in attempting all questions of this section. Most of times examiner place this section in front of question booklet. I suggest to attempt this section at last. Try to to learn the "Question Skipping" technique, never waste your limited time in attempting difficult questions. As every question carries equal marks so try to attempt easy questions. Surprisingly 80% of the questions are very easy and can be solved in fraction of seconds.
2. Never divide time equally among all sections
Normally there are four sections in IBPS exams, but quantitative aptitude section takes more time relatively. Where as English, General awareness and computer section takes relatively less time. You can devote 15 minutes more to each Quantitative and reasoning sections. It is wise to devote more time to quantitative aptitude as this is the most scoring section of exam.
3. Use shortcuts
Try to learn shortcut techniques while solving quantitative aptitude questions. Go to Buy Books and Study notes sections to get material to learn these techniques shortcut techniques. I also started shortcut techniques series, so stay updated.
