Talk with the professors (or instructors) first. Email, phone, in person, something, but talk with them about the program and ask them how to prepare.
Then:
Even if the instructors say that it will be easy for you, still get the textbooks (for each class) and read and study them. Do not expect it to be all easy. Prepare for it to be hard and use those textbooks to get yourself ready.
As I see it, you are looking at a technician program. Usually that does not require advanced math and does not require advanced programming knowledge. Usually. Not always, but usually. Talk with the instructors. Study the textbooks.
Try to make straight A's and try to succeed at this master's program so well that employers line up to hire you.
Thank you for asking.
