Some very interesting and broad discussion on this thread

, so I'll just put in my two cents rather than responding to a specific post I guess
In the end, many top achievers seem to be fairly blase about some of their achievements. This is particularly in relation to and competitions they have been placed in or done for fun. Their view of themselves and others' view of them will not change based on how they go in these competitions. If they get a medal, they don't go around telling everyone. In fact, often, they don't bother telling anyone.
Many can't imagine how much of an unnecessary burden it is for people to expect one to get 50s. Why would you build on that burden by hyping yourself up? If you know you have the capacity to do well, then just go ahead and do well and celebrate the ENTER score you've earnt. Why would you want people telling you how well you will do, knowing that there is every possibility that a stupid mistake or something could mean you don't get that 50, or that 99.95, or whatever it is that you are aiming for. At the same time, I find it difficult to relate to the pretending you got around 80% when you aced something, because that's just lying and people will think you're being shifty. It's ok for your peers to know you're fairly smart to some extent, as long as you don't show off too much and, as I said, hype yourself up. Generally if one doesn't want to show off one shouldn't ask others what they got (as the reciprocal question is: what did you get?) and only tell people if they ask you. But seeing as people do lie about their scores, it makes sense for them to not have their name in the paper, as then no-one will know the truth

Another question to ask yourself is this: are you studying for yourself or for others to praise you? If you are studying for the latter reason I would recommend you try adopting the former approach. You study to get into your desired course, to gain access to the scholarships that can make your life easier, to push your own limits, to learn and often to achieve. But you don't study so that you have something to brag about. When high achievers do achieve something like a high ENTER, they don't see the need to tell everyone about it, because they didn't work for it so that they could tell everyone about it. They also acknowledge, often, that in the long run there is much more to be done than the ENTER. Successful year 12 students aren't guaranteed to be successful later in life.
So in summary of the ramble: some amount of acknowledgement is cool, but often for academic achievers being put in the spotlight for one's achievements is not the reason one achieved those things. One doesn't need to be congratulated and raised to a pedestal to feel happy with oneself, all one needs is to be happy that they achieved what they wanted to.
