Score Choice for ACT?

<p>So I was reading the Rice's test requirement page and it said:
"The ACT does not condone splitting and combining subscores from multiple sittings, therefore, it is Rice’s policy to use the highest ACT composite score in admission consideration. "</p>

<p>Does that mean I can just send in my one best score from ACT or do I still have to send it all? I know for SATs they do not offer Score Choice but they never specifically mention about ACT.</p>

<p>HELP ME!</p>
