How to write Letters of Secretarial Practice in board examination

Hi aspirant,
For writing letter of secretrial practice you need to learn the performa (pattern)  of writing these letters. Make sure you attempt using this performa. Writing blank performa wont get you any marks,  you need to fill details, i.e. imaginary address etc. Make sure you mention only related details in the body of the letter. And making a boudary of letter is necessary. Hope this helps.
