Advertising & PR Preparation

Read these books:
1. Encyclopedia of Advertising and Public Relations.
2. Any book related to Journalism and Mass Communication. I recommend Arihant but the book has wrong answer keys.
3. Brand Equity supplement, comes in The Economic Times every Friday (I think)
4. Vir Bala Aggarwal
5. Book on public relations by Cutlip
6. General English and General Awareness.
