<p>The 2250 is obiviously better. Send that score in and DO NOT send in your ACT. A 33 ACT is equal to a little less than 2200 SAT. </p>
<p>I’m a big fan of just sending in your highest scores to colleges. Sending all scores will just make the admission officer look at more items that may give them an excuse to not accept you.</p>
<p>ACT is not concordable to SAT CR + M + W.
ACT is concordable to SAT CR + M.
ACT 33 combined ~ 1460-1510 SAT CR + M, which is about the same or a little lower (1470).
If they want to separate SAT CR from SAT M and take highest section (depends on college), sending both ACT and SAT would be beneficial.
33 ACT would be converted to a better SAT CR than 670</p>
<p>They are not concordable. If you belong to 99.99% in lift weighting that does not necessarily mean that perfect result is concordable to 99.99% in track and field and you could easily convert one to another by using a table. Those results are not well correlated. The same with ACT composite vs SAT CR + M + W</p>
<p>An example of concordable data - if you win Olympics in running 100m, you have very good chances to win Olympics in running 200m as well, but it is very unlikely you will win Olympics in running Marathon, it is even very unlikely you would be able to run Marathon at all. That is an example of non-concordable data.</p>
<p>10 SAT points could cost you $5K scholarship per year, especially if calculated in a non-traditional way. If you are not 100% sure this particular college would not value your ACT better than SAT, spend $10 per college to send ACT. You need to be absolutely crazy not to send ACT in case the results are close for the purpose of saving $10.</p>
