I didn't have and CV for showing and i completed my Bcom and now i pursuing Pdgm in finance and marketing So what thing i can do ?

Nothing to worry about it. You can make one CV from the achievements you have received till date. You have completed 10,10+2, your graduation, you have some interest in your life, you have some skills, just jot them down and compose a CV. Also mention in your qualification details about your PGDM course and just mention Pursuing (the year from start-end). There are no such rules that you can't do a CV.

Always remember that CV must have some of the characteristics. If you follow this characteristics then I think you will do great:

• Use formal image in your CV and provide a clear neat and clean signature in it.
• Choose the font very wisely. Don't take any font abruptly which destroys the official theme.
• Give your educational details in bullet manner and don't write long sentences about it.
• Try to mentions the skills you have in your life and what are the area of your interest. You must mention the interest related to the job profile in order to have a better chance.
• Be careful with spellings and don't do any error related to symbols, vocabularies etc.

This are some of the basic points you must take care of. You can read some of the newsfeeds in google about composing CV and implicate it. For more help we are always here for you.

I hope this answer helps. All the very best for your future endeavors!
