    Assessment and exam guidance

    Assessment Objectives

    AO1
    40%-50%

    Use and apply standard techniques. Students should be able to: accurately recall facts, terminology and definitions; use and interpret notation correctly; accurately carry out routine procedures or set tasks requiring multi-step solutions.

    AO2
    25%-30%

    Reason, interpret and communicate mathematically. Students should be able to: make deductions, inferences and draw conclusions from mathematical information; construct chains of reasoning to achieve a given result; interpret and communicate information accurately; present arguments and proofs; assess the validity of an argument and critically evaluate a given way of presenting information. Where problems require students to use and apply standard techniques or independently solve problems, a proportion of those marks is attributed to the corresponding assessment objective.

    AO3
    25%-30%

    Solve problems within mathematics and in other contexts. Students should be able to: translate problems in mathematical or non-mathematical contexts into a process or a series of mathematical processes; make and use connections between different parts of mathematics; interpret results in the context of the given problem; evaluate methods used and results obtained; evaluate solutions to identify how they may have been affected by assumptions made. Where problems require students to use and apply standard techniques or to reason, interpret and communicate mathematically, a proportion of those marks is attributed to the corresponding assessment objective.

    Tips and common mistakes

    Common Exam Mistakes

    Pitfalls to avoid in your exams

    • •Writing 0.375 as 375/100 instead of 375/1000. Correction: Count the decimal places carefully; three places means the denominator is 1000.
    • •Stopping at 375/1000 when the question asks for the simplest form. Correction: Always check if the numerator and denominator share common factors.
    • •Reading 3.5 as 3/5 rather than as three and a half (7/2). Correction: The number before the decimal point is a whole number.
    • •Dividing the denominator by the numerator, so turning 3/8 into 8 ÷ 3 = 2.666... instead of 3 ÷ 8 = 0.375. Correction: The fraction bar means divide the top by the bottom.
    • •multiplying by ten when the repeating block has two digits, so the tails do not line up and nothing cancels
    • •writing only the digits shown on the page rather than continuing the decimal, which hides the fact that the tails are identical
    • •leaving the answer as 45/99 when the question asks for the simplest form
    • •treating a decimal such as 0.375 as recurring and starting the algebra on it when short cancelling would finish the job

    Top Examiner Tips

    Expert advice for exam success

    • •Learn common conversions by heart, such as 1/8 = 0.125, 1/4 = 0.25, and 3/4 = 0.75, to save time in non-calculator questions.
    • •Check a conversion by multiplying back: if you found 3/8 = 0.375, check that 0.375 × 8 = 3.
    • •When ordering a list of mixed decimals and fractions, it is usually easiest to convert everything to decimals first, order them, then write the answer using the original numbers.
    • •Write both lines one under the other with the decimal points aligned, so the subtraction is obviously exact.
    • •Test your fraction on the calculator when the paper allows one; it should reproduce the recurring digits.
    • •If the question says show that, finish with a line naming the fraction you were asked to reach rather than stopping at the algebra.
    • •Sketch a bar split into the parts and label one part; most ratio questions then read straight off the bar.
    • •Add your final shares together and compare with the total in the question as a check before moving on.
