According to this - ans is monosacchrides. Sugars looks vague.

Glucose is a monosaccharides. YES

What do you think is the maximum percentage anyone gets in Physics and Chemistry? Do people get 100%?
Because if they do, that would be a problem for us. The grade thresholds will be raised. .-.

According to the revision checklist, it's simple sugars.

i wrote 10 how 22?explain brotha

Same here

 

[asadalam]

That second one is a bit tricky. I went with does not conduct electricity when solid. :/

I wrote the same.Also ninhydrin is a locating agent,though the words isnt in our syllabus but we had to write locating agent at least.

Damn it. Knew it. I wrote ''Sugars''. Will i get the mark?

We gave it our all.Thats enough.And dont worry they arent raised that much,there are still some U graders in the world!

 

[Ram97]

How much marks were for the carbohydrates part??

 

[DaniyalK]

Damn it. Knew it. I wrote ''Sugars''. Will i get the mark?

Perhaps. I can imagine the mark scheme reading "(simple) sugars"

But do people get 100%? I mean that's impossible right?

 

[DaniyalK]

But do people get 100%? I mean that's impossible right?

Some of the students who receive a distinction do get 100%.

 

[Dark Destination]

Perhaps. I can imagine the mark scheme reading "(simple) sugars"

And i can image it reading:

Simple sugars/Reducing sugars

ALLOW: Monosaccharides.

NOT: ''Sugars''

- And btw, every carbohydrate is a sugar. Starch is a COMPLEX sugar. Cellulose too. Should have written ''Simple''.. >.< I'm such an idiot. I always write more stuff, but idk why i didn't write here.

 

[asadalam]

Not really.Its easy enough for the geniuses i mean o level chem is the easiest of the science lot,and people probably get 100 out of preparation and luck.

 

[Dark Destination]

But you don't need 100% for a distinction. What if the highest percentage is like 98? That person will get a distinction, then. Right?

I agree sugars is a vague term,but dont lose heart,one mark means nothing!

Yes,but somewhere there is a freak who gets 100%

 

[asadalam]

Yep.

But it has been said that at times multiple people have got 100% (esp in Maths) and they have had to sort it out via checking who's methods were the best - most precise etc. Just a rumour that - but looks believable enough.

Its true,my maths sir saidthat.

 

[Dark Destination]

Who told you that? Perfect paper - every point in MS matches. Ditto done. A teacher would be able to get 100% - why not some all A* student too :v

This isn't English or Urdu ke full marks ka scene nae hai

No matter what a person does, he can get one mcq wrong, or lose two marks or something. So it is very hard.

That would be unfair. Everyone who gets 100, gets a distinction.
It would be weird not giving a person that award, even when he got full marks.

But seriously. That happens in Maths. Never in Chemistry/Physics.

The probability is high,there are literally 1000s of students appearing,and some of them will get all the tricky ones right.
