Hey Mohak! 

Purchase the Manorama of this year, to have better knowledge of IIFT’s GK and Current Affair. Secondly, go through international Business related news through Mint and Economic Times. Plus, you can go through previous year question paper. As many questions are repetitive, atleast in GK section of the 2017 paper. Many GK questions were repetitive. 

Few common questions like companies and their taglines in the match the following or logo. Few important economic policies also you should know. Best wishes! 

Hello dear, 

I would suggest you to read newspaper on a regular basis, watch english news daily and keep yourself updated with what is going on. You can also download many apps like TOI, Inshort etc, which will pop notifications up as and when there is a new information. 

All the best!
