To clear exams for clerical jobs in SBI or other banks you have to follow a particular strategy so that you do not walk on the wrong path and lose your opportunity. Some points are:

1. First of all you should be thorough with the syllabus. You should know that English exam certain topics have been given priority over other topics in the past many years. So you should know what topics you have to prepare first so that you have a strong hand over those topics.

2. You should improve your numerical ability which can be done by practicing questions over and over again so that there are less chances of making calculation errors.

3. You should also develop the habit of reading newspapers, magazines and blogs for better understanding.

4. You should also keep a formula notebook for revision.
