Top Law Schools

I know people often say to go ahead and submit applications if they're done even if waiting on their LSAT score because it'll get sent along to schools automatically - does the same logic apply for LORs? I have 2 of mine already uploaded and the third (my most important one which I'm using for every school) should be uploaded within the week.

Will it matter at all if I go ahead and submit applications? Tired of looking at them 30 times a day anxiously waiting to submit...

Be careful if you choose to, some schools say they will not wait for an optional third 2nd or 3rd letter before moving along in their review process.
