    There's always a first! I mean there have been Physics papers where the threshold has become 48 when the paper was really hard! Can happen for Chemistry as well. Lot of people at our Centre found it hard!

    Discuss Chem P42 !!

    I think it's one of the toughest Chem paper 4 I have ever done! The 1st Organic question required to think but the 2nd Organic question was a bit easy. Applications, I think I got part of the Lead Acid battery wrong, and I hope my reasoning for the Enviromental part is ok. The other parts of...

    Revision Notes for CHEMISTRY APPLICATIONS (P4 SEC 2 A)

    Our teachers realised that there are mistakes and made us seperate notes for the topics that were poorly written. Especially for people who have no prior Biology knowledge except for O Level Biology the Biochemistry topics are difficult to grasp at first and the Applications Booklet doesn't...

    any guess about AS phy p2 and chem p1

    Don't work on Guesses. These papers are not leaked. For Chem 1 go through the past papers and revise your core topics. It's a small section of work. Work through the past papers from 2005 onwards and you should be fine if you score 30+ for all of them. If you get less try revising the topics...

    Addition Copolymers & Chem Help

    Can anyone explain to me how Addition Copolymers work and how to identify whether a polymer is an Addition copolymer or a condesation polymer? Another question is if an amino acid has an overall -ve charge lets 2 COO- and only 1 NH3+ then how does it's reaction vary when you react with acids...

    How's Chemistry Paper 52?

    Just a few clarifications. If you changed both the mass of KCl and Water it does not matter, as long as you say what range of molarity you are covering. I covered a range from 2mol per kg to 67 mol to kg and I varied BOTH the mass of KCl and water. There is no hard and fast rule to which one...

    How's Chemistry Paper 52?

    Actually if you said that 0.8 is close to 1 AND INCLUDING EXPERIMENTAL ERRORS then the equation is valid you'll get your marks. However if you just said that 0.8 is close to 1 then you probably won't get your marks.

    This is why should never work on Predictions

    Chemistry Paper 2 was a perfect example of why you should cover the whole syllabus and not predictions. It might have been an easy paper, but none of the predictions were right. Neither were the predictions for Paper 5. Everyone don't look at Guess Papers and predictions except for Practicals...
