Question 10 Most candidates understood the initial step, but many omitted the brackets and never recovered. Part iii Those candidates who used their graph to find the gradient and the intercept often went on to score full marks in this part. Of those who spotted both relationships, a good proportion made a mess of simplifying the fraction, often resulting in a final answer of. Question 2 Part i This was done very well. Please can anyone help, Integration, c3 mei, ocr maths!?!? Policies and guidelines Contact us.

A common error was to omit the minus sign from the first term. The FMSP revision videos for MEI are topic-based videos featuring an explanation of the specifications and some example examination questions. However, Centres which are new to the scheme are strongly recommended to use the tasks published by MEI while they are familiarising themselves with the nature of coursework. The very latest A level papers can only be accessed from the OCR Interchange or through teacher access to each unit within. Centres are advised that using a graphical calculator to evaluate a definite integral or to solve an equation eg question 10 will earn no credit unless the relevant working is presented. A surprising number tried squaring top and bottom, or concocted an equation which they attempted to solve. Candidates were expected to comment on the model continuing to predict an ever increasing rate of reduction in the thickness of the ice, in spite of the fact that at some point all the ice will have melted.

Those who adopted other methods such as simultaneous equations often went astray, and obtaining a positive value for the Y- intercept or a large value for the gradient evidently did not cause concern. It is differentiap to see some candidates misquoting formulae that are given to them in the booklet. Year Number of years since 5 10 15 20 25 30 35 40 45 50 t Reduction in thickness since 0.

Method marks are not usually lost for numerical errors, algebraic slips or errors in units. Part ii This was very well done. By and large the correct formulae were used and the entire solution was worked in radians, nearly always resulting in full marks.

The units for x and y are metres. Part v Many candidates wrote sensible responses to this question.


Question 2 Part i This was done very well. Part iii This was generally well done.
