FYA

FYA is NEVER time apportioned. You are still not working through the OT course notes - see chapter 5 last note in section 2!

thanks Sir I did work through OT course. I sometimes forget.

That is understandable as there is a huge amount to learn but when you have a problem like that go back to the notes and find the answer from there - then hopefully the memory will remain - this is how we learn! Keep working hard.
