Is the Act with writing subsitutable for the Subject tests?

<p>I’m looking to apply the BC and I’ve heard that the act with writing is a suitable replacement for the Sat subject tests. I was just wondering if anyone could clarify this for me before i register for the test in June. If i can, then it would save me money and time i could spend doing something far more entertaining.
Thanks!</p>

<p>I got in and I submitted only ACT with writing.</p>
