Do I need to send EVERY ACT score - including the ones about writing.

I have taken the ACT 3 times and will be taking it one last time in September.

I took the ACT without the writing for 2 of those 3 times. On the freshman application guide, it says that they want all scores for ACT PLUS WRITING.

Should I also send the two ACT scores without writing? Do I have to?

Also - my scores have gone up significantly from test to test. I have gone from a 25 to a 30 to a 32. I am super confident my score will go up again (I have been practicing on the science part which is what brings my score down so much). I don’t know if the fact that I will have taken the ACT 4 times will make a difference, but I think that taking it a last time is worth it. My 32 was also without writing, so I would need to retake it for that reason alone.

All scores must be sent
