Sorry guys but i did 31 and it was so easy!!!

Paper 32 was a total treat !!!
Except for time management which was a bit tricky since the paper was lengthy for me, the actual questions weren't that hard I thought.

Wasn't as long as BIo and Phy paper 3. Pretty easy actually. The hard questions weren't really that hard to figure out.

I knew people like u will say it is short but in my view u may have done many questions wrong because for almost the whole exam u had to read the question properly..
This takes sometime and cause delay therefore u say it was short
It was the same in my school one guy said the same words like you and at the end we found out that he was filled with lot of mistakes

 

[gary221]

oh god i just figured out a dumb mistake i made in the cells question
:x :x :x :x :x

Paper was pretty easy for me. It was short but like someone above said, you had to think about the questions and read them properly so I didn't finish quickly.

The hardest question in my opinion was the one asking why using biodiesel is has less effect on the carbon dioxide concentration in air than using fossil fuels.

My answer was along the lines of biodiesel is made from methanol which is made from those very same fossil fuels that release carbon dioxide into the air.

Anyone else use the same idea to answer that question. What did you guys write?

 

[burndtjamb]

I used a different idea. At first I was thinking that biodiesel is made from vegetable oil which comes from plants which have livewd recently. These plants absorb carbon dioxide from the atmosphere, so when they are burned it is released again.

But, during the exam I was thinking that crude oil comes from dead organic matter (including plants) so I panicked a bit and wrote something else, though I think I should've put what I just wrote as my answer

What I ended us writing was that heat is required to separate crude oil, so fossil fuels are burned to provide this heat, which in turn releases CO2. Though I pretty much made that answer up, I had never thought about where that heat comes from when I was revising so I really don't know if that's how it is actually produced.
