@SaphireNY That is the case. Some schools only use certain section scores for the conversion instead of the full composite. ACT.org and CB have their own chart and each school may use a different chart for their preference. Here is one for UT Austin:

If you have never heard of it, now you do. In your post #23, you did mention " in some score charts a 2320 is the upper range of 34". So you are aware of the different conversion charts and yet you said " NEVER heard of the correlation changing based on the college". Just wonder where do you see the different conversion charts then? LOL.
