our exam is after 2 and half months
and our chemistry teacher is new...so we told her to finish the syllabus this term so we can work on the past papers next term.

Will u be giving the AS exams this session??
by the way the reason our teacher is going at this speed is so that we understand everything clearly...but completing the syllabus in this term itself...i think that's nt gud...u might have all the things jumbled in ur mind...i dont knoow..by the way after completing each chapter we keep one day to do the questions in the pastpapers from 2002-2009 of that chapter!! so going side by side...and most probably we'll have our annual exams by the first week of april and then we'll start with A2 syllabus!!we'll be giving the exams of AS / A2 next year together!!

oh so u'll be giving the exam of As and A2 together.
i'll be giving the As june 2011.
and i think doing the syllabus this term is fine, cuz the syllabus has most chapters form IGCSE plus some new info so it wont be too much borden.
