ST Math Support is open Monday through Friday, 5 am to 5 pm Pacific time. You can reach ST Math Support by email at firstname.lastname@example.org or call us at (888) 491-6603 to get immediate support. Our goal is to respond to all emails within one business day, but when things get especially busy it might take us a little longer. We will get back to you as soon as possible. Please provide us with as much information as possible to help with your questions.
