Essay question (undergrad)

<p>For Undergrad admission essay. Since it is required that an applicant must submit 2 essays, can I write Essay C and Essay S? (does Essay S(special circumstance) count as one essay? or do I have to write another one in topic A, B, D?)</p>

<p>Also, For Essay S - what does it mean by “not available through ApplyTexas”?</p>

<p>Thanks</p>
