emailing admissions officers

<p>I want the colleges that I want to go to to atleast have a clue as to who I am. I am currently a sophomore, if I have questions about a perticular school, should I contact an admissions officer now, or is it too early in the process. I have already recieved letters from some schools wanting me to consider applying to their school or fill out a survey, but thats different than me starting a conversation with them. Should I contact them?</p>
