Hi Pat, I have taken the exams twice which both I passed but unfortunately I did make the final cut.
Tips
Interview: Be confident, Eye Contact, be honest, smile.. do not worry about technical questions just be honest if you do not know, what they are looking is the way you carry yourself, the way you answer the confidence and leadership qualities
Psychomotor: Focus, wear comfy clothes, you may practice flipping chips if you want
Written exams: I don't know if it still in Makati Med, try to review your math, if you have reviewers from college try to answer it for a refresher
Just don't pressure yourself
By the way how much is the cost now and how many cadets would they be getting?
