Here are some tips on how you can implement your exam strategy.
If you are preparing at the last minute, it is better that you watch videos for subjects instead of reading from books. Audio and visual information stays in your mind for a long time. Along with that, it will also save your time.
You can download reading materials from online sources. Most of the sites have free GK and study materials for MBA exams.
You don't need to panic. 30 days are enough for cracking IIFT if you study with full dedication.
All the best
