Can you double deposit ? yes you can, will some say it is not the right thing to do, yep . If I am reading your post correctly you do not have to deposit at school one until Aug1, a commit letter is non binding. I have agreed that colleges do this all the time it is called a waitlist, there is a debate going on as mentioned by others, but can you yes. You will have to make up your mind and let one school know when that happens, it seems your looking for about 30 days until you find out if your spring school will let you in earlier. You usually lose your deposit , but in your case you only have to pay one dep on may1. Can you do this YES, should you do this, that is open to debate from a ethics point of view. What are the schools?
