Hi,
In bank PO examination, you are required to first clear the clerk examination. No, there is no need to submit any computer certificate. You need it only for the clerical post. It is clearly mentioned that those who didn't study computers at a degree level don't need to submit any certificate even for clerical post . So in conclusion, it is not necessary to have computer certicate for bank PO.
I hope this helps,
All the best.
