Hi
Questions will not repeat however structure remains more or less the same. If you see past few years IIFT papers you will get a good idea about the topics which carry significant weightage in IIFT . Try to strategize accordingly.
For GK also understand what is asked in the paper and then prepare for it, try to appear for all the IIFT mocks .
