Thank you! But I see that the link isn't working. Could you kindly have a look over it once?

Kindly copy and paste this link on a different tab.

Ah, alright. How dunce of me! Yes, it worked. Thank you so much, Priyanka. Apropos, if you don't mind; as I'm craving to get myself apprised regarding it but unable to get any satisfactory answer; which is, apart from BFS [Eng, Eco, BST & Maths - in my case for Eco B.A. (Hons.)], for the sake of my AISSCE %, can Physical Education marks replace that of my Accountancy (low marks, not failed: please note!) as my fifth subject n' hence, making Accountancy (let's assume, a score of 70) the sixth subject in this case?
Hope you could help me. Your solemn reply's utterly solicited. Thanks again!

Physical Education's marks is 99. Accountancy's marks is 70.

If you add Physical Education in your best four then 2.5% will be deducted from your aggregate percentage (best three + Physical Education).
Am I clear??

Precisely, Priyanka. I am but afraid that my enquiry is a bit unclear to you. Pardon my French, I am not asking what you meant. Obviously, you did enlighten me to my first enquiry. On the other facet, what I asked (in my comment) the second time, is that "WHETHER PHY. ED. MARKS (say, 99) COULD REPLACE THAT OF MY ACCOUNTANCY, MAKING THE FORMER AND LATTER, 5TH & 6TH SUBJECTS RESPECTIVELY?" Here, one's Accountancy's marks is low (so, let's say 70: not 'failed') which could take a bust in AISSCE PERCENTAGE CALCULATION on the basis of 5 subjects.
I don't please to include Physical Education marks, shall I assert it clear, in my BEST OF FOUR SUBJECTS. My BFS would be: English (one language), Economics (the selected discipline), Mathematics (I do want to include it in my BFS) & Business Studies (I reckon BST is in the LIST A of 'Academic Subjects').
Pardon me inconvenience you hitherto long with such rigmarole exaggeration; I do ache to get your response on the matter, if expedient. Thanks!
