A few words about Prelims 2012
Just a sideline - my tuition services are available for 2020. I provide dedicated tuition services to my students. Sms me at 82875873.Some questions from A level chem papers last year were quite similar to university textbooks end of chapter exercises. I shall be writing again soon hopefully.
The trick in A levels is to master your basics real fast and practise tough papers. Cambridge has used ideas from old S papers and H3 papers. So you may wanna ask your teachers for some of the papers, if you are game for the challenge.
