It is definitely ‘worth’ preparing for the IIFT. But for a confused mind, it is better to first gain work experience which will strengthen your resolve.
But maybe you specifically want to emphasize the ‘fresher’ part of your query. Then I would say that if you want to pursue an MBA, definitely prepare for IIFT. It is a very subjective choice. People who find fulfillment in their jobs need not go for an MBA, but if one feels that MBA is the right option for us, be it a fresher or an experienced person, preparing for IIFT is worth it.
Yes, you can prepare for IIFT as a fresher. It is not necessary to have work experience in order to do an MBA in India. So, ‘worth’ is a subjective term in that sense. If you have a goal, you can definitely find a way to reach it with a little effort. Frasher or work-experienced candidates are kind of a short-sighted way to judge this.
If you are certain to opt for an MBA course then go for it. It is advised to first explore the industry, and figure out yourself whether you want to pursue it or not. So, you can know what will be the better option.
