SAT in January

Is it too late to do my SAT in January? Can I send my application till the 1st of January, but send the results from the SAT I take on Jan 23 2016?
Thank you in advance.

The first place you should look for that information is on Yale’s website: http://admissions.yale.edu/standardized-testing

So yes, you send in the Common Application indicating that you will be taking the January SAT test and you have your SAT scores sent directly to Yale. Your application will be considered incomplete until the test scores have been received, so you need to follow up with the College Board and make sure they have sent the scores and that Yale has received them.
