Reapplying as soon as possible might not be the best option.
Instead, I would suggest that you take your time and find out what are your weaknesses and improve yourself.
Improve yourself to a point where you have the best improvement you could have done before reapplying again. Rushing into reapplication while not being ready is possibly one of the biggest mistake you could make.
Quite a few of the current cadets are re-applicants. Most, if not all of them, spent at least 2 years after their first application to improve themselves and prepare for the interviews before reapplying again.
Only do it when you are ready to, not when they say you could.
