I did not say that he "needs" to go to uni, and nor did i attempt to dissuade him from applying.
My point was that as a young man with time on his side, why not go to uni and enjoy the benefits that it brings, and then apply to CTC as a 21 year old?
If he decides that its not for him or doesn't enjoy uni life, then he should apply and he may make a fantastic applicant, but hat least he gave uni a chance
