write in this statement in formal? Yes, sure I would love to explain how the CTC scores are averaged for both parents. The reason why the Parent1 scored 70% is due to QA has credited score for CF# 0160 & 0148 and that bumps up the score. But there were no QA finding under CF# 0160 & 0148 and QA indicated 'NA' on the CTC which means these two casual factors were not applicable or had no transportation payment and ancillary evaluation covering the RM. Therefore, the accuracy score is correct and has not been miscalculated. I hope this helps. Please see the following screenshot for your reference
