Actually dont focus on how many SATAs you get. I got about 10 and still passed with 75 qns. SATAs as u know are about knowing the material and not over thinking the qn. I rather got alot of teaching...
Your predicament seems so similar to mine.. Going into the exam on Wednesday i was soooo.. Anxious! Tried to calm myself with deep breathing, distraction, nothing worked! Went in and sat for the exam...
