Beforethe grading scheme varied between examination boards, but typically there were "pass" grades of 1 to 6 and "fail" grades of 7 to 9. However the grades were not displayed on certificates. The CSE was graded on a numerical scale from 1 to 5, with 1 being the highest, and 5 being the lowest passing grade.
I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4. Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long!
Some quizzes, particularly the compilations, are quite large and take some time to download.
Links to specific GCSE chemistry notes and quizzes about the topic in question have been added, and from these pages, you may find other links to more useful material linked to the topic.

Chemistry Paper 4, Topic 13 "The rate and extent of chemical change" Appreciate that chemical reactions can occur at vastly different rates. Whilst the reactivity of chemicals is a significant factor in how fast chemical reactions proceed, there are many variables that can be manipulated in order to speed them up or slow them down.
Chemical reactions may also be reversible and therefore the effect of different variables needs to be established in order to identify how to maximise the yield of desired product. Understanding energy changes that accompany chemical reactions is important for this process.
In industry, chemists and chemical engineers determine the effect of different variables on reaction rate and yield of product. Whilst there may be compromises to be made, they carry out optimisation processes to ensure that enough product is produced within a sufficient time, and in an energy efficient way.
Factors affecting the rate of a chemical reaction - temperature, concentration, particle size, catalysts etc. Chemistry Paper 4, Topic 13 "The rate and extent of chemical change" 6.
You should be able to: In the context of rates of reaction data, you must be able to Recognise and use expressions in decimal form. Use ratios, fractions and percentages. Make estimates of the results of simple calculations. Translate information between graphical and numeric form.
Plot two variables from experimental or other data.
Determine the slope and intercept of a linear graph. Draw and use the slope of a tangent to a curve as a measure of rate of change.Cox Report English for ages 5 to [page 4] Programmes of study. 8 The purpose of programmes of study is to establish the matters, skills and processes which pupils should be taught in order to achieve the attainment targets.

The General Certificate of Secondary Education (GCSE) is an academic qualification, generally taken in a number of subjects by pupils in secondary education in England, Wales and Northern Ireland.
Each GCSE qualification is in a particular subject, and stands alone, but a suite of such qualifications (or their equivalents) are generally accepted as the record of achievement at the age of
