Yes. As a grad and an admissions adviser, I was prepared for the level of effort. However, for your child it is difficult to fully convey the enormity of the process in a way that they will understand until they too have gone through the process. Sadly, there are too many variables to know where you stand and after doing all of it, you can get the TWE and it all be for nothing. Regardless of the outcome, the candidates do benefit personally by going through the exercise and the interviews, but it is far more work than a regular college. The payoff is huge if you receive the appointment, but most candidates are so invested by the time a decision is made, there are no other possible outcomes other than elation or devastation.
I remind my DS and candidates that I have advised that I opened 5 TWE and a medical DQ. It isn't over until you age out or reach the end of the medical road with a condition they are not ready to waive. Those who reapply after their initial admissions cycle have more maturity (which shows in interviews and essays), are typically better equipped academically and from maturity, and demonstrate significant motivation towards the school and a life of service to the admissions panel.
