how to prepare for GK for XAT,IIFT exams??

hi .i am preparing for iift .so sharing about that . first have a look at the previous year question paper. 1.for current affairs use apps like testbook's current affairs/bsc match point/or any other u prefer .but keep in mind what kind of gk they ask from previous year. 2.for static u can start collecting data on you own like ceo list, logos, tag line, various bussiness blocks ,sports terms,tournaments various prizes,(ramon magsaysay seems to be their favourite) etc.google the topics .u will find a pdf on net.cracu also has lot of the lists . 3.i found that they ask 1 or 2 odd question from history and science.they are mostly about revolution or a chemical compound. so i wont suggest going in length about various aspect of geography science ,history, polity. 4.buy a book like lucent's Gk and go through some sections from there.like compounds common name.geography section of it is must. 5.u can also take handa ka fanda gk course it costs around 500 .its quite useful as a building block but dont depend completely on it.One problem is the content on Handa's site is not downloadable.The UI is just too messed up but you can pick up lot of good points from there. All the best.
