I have comprehensive notes about sulfuric acid from last year, when I have the chance I'll scan and upload them.

Yes, I have heard of that too. However, that is a misguided strategy, because on the exam you will have the same general question as everyone else, just that the answers differ, depending on your chosen chemical. This makes studying 2 chemicals pointless. The only reason why you'd study 2 detailed studies (in Physics, for example) is because you might get an easier question, but since (according to the sample exam), the question regarding the chemical will be the same, there will be no advantage in having that extra choice.

Also, you cant answer half of the general question with one chemical, and the other half with another chemical. Hence, you should just pick 1 and stick with it.

Unit 3 did not talk about the production of ethene. It talked about some of the uses of ethene.

The old course featured a section on Sulfuric acid in Unit 3.

Okay, well the "uses of ethene" is part of this unit, if you choose to do ethene. You also need to know the production of ethene though.

If you can write the chemical formula of your chosen chemical, you win 1 mark on the Sample Exam.
