I would like to know about suitability of the theoretical part in the F9 note. Actually I am reading your F9 note, very nice in fact, for clear understanding & assistance for mathematical solution of F9. But can I use the theoretical discussion in the note as answers for the exam question(theoretical) in order to get full marks? plz kindly inform me.
Yes you can, although it is in the free lectures that I expand and explain the notes where relevant – you should not just use the notes on their own.
The lectures and notes together provide enough to pass the exam well (both calculation and written parts) provided that you do also have a Revision Kit from one of the approved providers in order to be able to practice lots of exam standard questions.
