Question about ACT

I am so confused with Georgia Tech’s way of evaluating my ACT.

This is my final score:

Composite: 31
English:33
Math:36
Reading: 26
Science: 29
English+Writing(8): 30

If GT doesn’t count scores from Reading and Science, is my new composite score (33+36+30)/3 = 33???

Also, GT says the mid 50% of the applicants accepted have their ACT scores between 30 and 33. Are these scores based off of the original composite score, or the average of English+Math+Writing?

They don’t calculate a new composite score for you lol. They just look attempt separately and ignore science and reading.
