If i prepration for cgl and can i cleared the bank po exam

To prepare simultaneously for both the exams and to be able to crack them you must be really good at two key subjects- Maths and English language.

You can follow the below:

Read a lot. Newspapers, magazines, novels, journals, biographies, whatever it could be. Decide your interest and start reading. Keep your senses of observation high while reading.

Develop a very good speed to solve question (basically these are tricks and formulas) and Solve questions as much as possible with accuracy.

The preparartion cannot be exact but is similar.

Good Luck.
