Hi Guys,
Am planning to give my GMAT in the next month and had some very basic queries regarding choosing the schools on the exam day. I know choosing 5 schools on test day would be the last thing on ur mind and my questions below would seem stupid , but still wanted to satify my curiosity

1. Is choosing those 5 schools on test day mandatory ? because right now am just giving the exam but not planning to apply anywhere for the next 1 year. Now, since I have not really researched about what programs to apply, do I just select any 5 random schools based on how popular they are or something ?
2. So, if I do choose 5 schools on test day, the gmac website says that they will receive the scores within 20 days or so. Again the question that since I am not going to apply for the next 1 year what will those schools do with my scores? and when I do apply next year, how does the process of telling them about that you received my scores 1 year back or so works ?
3. Lastly, for the additional scores that I would request once I decide to apply to schools - the gmac website gives a number of options regarding that. So, I wanted to know if the schools require the scores to be sent to them directly by GMAC or we can request some copies from GMAC and send across those with our applications ? :S How does it work ?
Thanks in advance to anyone who would spare some time to clear my doubts
