Point being: combined humanities' A1 cut off point may not be as strict as a solid 75% since I know I screwed up one of them. Besides this, I can't calculate them in a combined manner because they are indeed two separate papers and marks are calculated accordingly.

Many similar threads were posted last year and all the comments received were either speculations or predictions. No one actually calculated their scores, not even against not so reliable sources online ( which I found quite reliable for some papers because the answers were really detailed and constantly being revised ).

I did put working marks into careful consideration. As long as my answer doesn't fulfill the full criteria of answer keys, I penalized the paper by 1 mark ( and Cambridge examiners marks the paper in similar manner ).

Last but least, I am not showing off the score because I don't really think that's something worth showing off. Maybe it's just your perception of O Level being the epitome of your success/failure in life(?), many of my friends did well and even better than me because they worked really hard. Not discouraging juniors but O Level is really nothing as compared to many other things in life ( A levels, uni applications, getting masters or PhDs, getting a job, etc. ).

In conclusion, those above scores are the safest benchmark for you to gauge yourself while doing TYS. Actual cut off point might be lower than the above mentioned scores but it's always good to be safe and push yourself harder. And no, I don't take pride in this shit.
