It would seem that a significant minority did not connect this part with earlier parts of the question. Remember me on this computer. 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. When a candidate adopts a method which does not correspond to the mark scheme, award marks according to the spirit of the basic scheme; if you are in any doubt whatsoever especially if several marks or candidates are involved you should contact your Team Leader. 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.
Unfortunately a few candidates stopped at f 60 and lost both marks. Grade boundaries Raw marks and UMS marks for grade boundaries for your chosen unit will be shown here. For unitised qualifications, both the unit uniform marks and grades, and the final uniform mark and grade are given on the results slip. Give your answer correct to 3 decimal places. Enter the email address you signed up with and we’ll email you a reset link. As these reforms are taking place in stages, many students will be taking a combination of modular and linear courses, with AS Levels still being part of an A Level in older modular courses. A small number left the calculator in radian mode and lost the final mark; a very small number tried to use Pythagoras or lost their way after earning the first method mark.
The paper was accessible to a large majority of the candidates, and most candidates seemed well-prepared.

Remember that the mark scheme is designed to assist in marking incorrect solutions. As these reforms are taking place in stages, many students will be taking a combination of modular and linear courses, with AS Levels still being part of an A Level in older modular courses. Both papers are marked out of 80 and both students score Choose your unit First choose your unit by selecting the qualification type, series, qualification and unit from the dropdowns. Question 2 Part i This was done very well.
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.
Some candidates rounded off their calculator value, and then over-specified their final values Therefore, for this unit, Sally achieves an A and Peter achieves a B. Remember me on this computer. Correct but unfamiliar or unexpected methods are often signalled by a coursesork result following an apparently incorrect method.
Peter therefore has u,s raw marks with the A boundary for his unit set at Since exam papers can vary in difficulty from one series to the next, a common scale is used called the uniform mark scale or UMS to ensure marks gained on an easier paper do not advantage candidates compared with those who gain marks on a harder paper.
When this is converted into UMS, he has 60 uniform marks. Annotations ocrr abbreviations Annotation in scoris Meaning Blank Page — this annotation must be used on all blank pages within an answer booklet structured or unstructured and on each page of an additional object where there is no candidate response.
A number of countries use A Levels as a school-leaving qualification. Log In Sign Up. Sometimes the answer to one part of a question is used in a later part of the same question.
Calculating your grade – OCR
How is the UMS calculated? Write down two equations in a and r, where a is the first term and r is the common ratio. A accuracy marks are not given for answers obtained from incorrect working.
Some candidates applied the scale factor to both values. Accuracy marks cannot be given unless the associated Method mark is earned or implied. A Level is considered more academically challenging than that of the first year. Year Number of years since 5 10 15 20 25 30 35 40 45 50 t Reduction in thickness since 0. When A or B marks are awarded for work at an intermediate stage of a solution, there may be various alternatives that are equally acceptable.

Question 7 Most candidates wrote down the required equations, and most went on to eliminate one of the variables correctly. The table shows the reduction in thickness from its measurement in Any blank pages are couursework. A tiny minority gave all values to a different degree of accuracy to the one requested, thus losing two easy marks — although credit was still available for the plots and the line.
A very few differentiated instead of integrating.

The AS Level is now a separate qualification and is not required for an A Level award, although it still encompasses the first year of the full Cougsework Level content. Some candidates slipped up finding the value of uums, and a few made sign errors when finishing off.
Some candidates needlessly went on to obtain the equation of the chord, and then differentiated it just to convince themselves that the gradient really was — 6, and a few went straight to finding the equation of the chord, and then left the answer embedded, which cost the accuracy mark. The sum to infinity of this progression is
