<p>Can you tell by doing simple average of the 4 session score to get the composite score? The composite score does not use the writing score, but some schools like Stanford would look at the combined writing score separately. By the way, most schools do not superscore ACT. Stanford would look at the best single sitting composite and the combined writing scores separately (i.e. can be from different test date). While many other school would only look at single sitting score with writing included, so even you get a much higher composite in ACT without writing, it may not help.</p>
