What do I do?

I got accepted into Berkshire, Loomis, Kent ( I got a merit scholarship what does that mean), Mercersburg, Saint Andrews, the Hill and Brooks.

Can someone give some advice?

Ask in a week.

A merit scholarship is money a school offers you on the basis of some talent/quality you have that is valued by the school. It is not need-based and effectively reduces the cost to attend the school. The school is probably offering the merit scholarship to try to make it more likely that you will choose to attend.

If finances are an issue, seriously consider the place that gave you $$. That also indicates that they think you will do very well there. As they say, love the school that loves you. Make sure they are on your revisit list.

Congratulations!
Plan on attending as many visit back days as you can logistically manage (and that make sense based on any aid offers).
Those revisit days provide a much, much clearer vision of the culture of the school, and your fit. They are also great fun!

MODERATOR’S NOTE:
See the following thread, and ask again in a week. Closing thread.
