Dear Palash,

Prepare well for the licence Exams, so that no idiot can fail you for not bribing them

Secondly , Take a camera and shoot the pic of every idiot who asks for a bribe, this should frighten them. Or shout on them and let public near you know that he is a corrupt. This is the best fight against corrupts. brand them loudly that they are corrupts.

if u learn well and do well , they cannot fail you. Personal experience.

Thanks,
Vijay
