Can I use both black and blue pens in my mains answer sheet for TNPSC exams?

The Board of TNPSC has allowed only one of the two colours i.e.blue or black. It should be ball point or gel ink or fountain pen. You should use only any of the two colours for all the usage viz side heading, highlighting, writing points etc..

You should use only one colour either black or blue. You cannot use both the colours in your mains answer sheet. It is advised to carry extra pens of the same colour you prefer to write.
