It is far too early for you to be obsessing over colleges.
However, I don’t see anything wrong with spending 5 minutes – and no more than that – learning about colleges each day.
So buy a Fiske college guide. Read about one school each day – about five minutes of reading.
Learn about all the schools. Then, in about 4-5 years, when it is time for you to be seriously considering your college applications, you will be armed with at least a little bit of knowledge about every school in that book. If you have forgotten – there is probably far too much knowledge in that book to retain for several years – you will still have the book to use as a reference/reminder.
