Overreacted but I'm happy to get some MCQs right
yesI wrote NH4+ is it correct
I heard somewhere that if you get 160 marks or so, you can get regional distinction.
Chemistry but it's almost the same for English, Physics and Bio. It makes 92 percent or something.160 marks in which subject
I heard somewhere that if you get 160 marks or so, you can get regional distinction.
because we dont know the proportion of CaCO3 and Mg(OH)2. and not all the HCl reacted withCaCO3 some reacted with Mg(OH)2
They have set grade thresholds beforehand according to the difficulty so I heard it's 160 marks this time
I used the Mr method. Mr of CaCO3 divided by Mr of CaCO3+ Mg(OH)2 x 0.500.
The thresholds are set after the papers are checked depending on how the candidates performed. And the distinction is set according to the highest marks, it could be 100%, 96% or even 92%.
