Which scores to send?

First time I scored a 29 C in March 2015 then I scored a 33 C in October 2015. Should I send both to show colleges my level of improvement, or is it just safe to send the latter score?

Also, I scored 1 point higher in the math section and a higher essay score on the former test. Should I send both in hopes that the colleges I’m applying to (Cornell, JHU, NYU) will superscore?

Just send the 33.
