2 Guidance notes for Sample Paper Mark Schemes Level 1 and Level 2 Notes: The mark scheme has been carefully constructed to avoid penalising candidates repeatedly for similar errors: 1) Principle of follow through applies throughout unless otherwise stated. This allows the candidates to gain credit for subsequent correct calculation based on a previous incorrect answer. 2) Units or numbers shown in brackets on the mark scheme are not required for the awarding of mark/s on the candidate s paper. However, if a candidate states units they must be correct: eg 24(cm) means accept 24cm or 24 but not 24m eg ( )72.5(0) means accept or 72.5 or or ) URT means unrounded, rounded or truncated; the underlining defines the acceptable limit of approximation: eg URT (U is the unrounded version) the following are acceptable: 860 (T) or 861 (R) (T) or (R) or (T) or (R) or (R) or (U) but not eg 900. Total marks available: 75 Indicative pass mark: 45 (or above/below)

3 NB incorrect money format given as an answer should only be penalised once on the whole paper and will lose 1 mark. Do not penalise any subsequent incorrect format. Section 1 Question Total marks Marks Marks awarded for Q1 3 1 evidence of systematic/methodical plan indicated in sequence eg sequential list or simple flow chart or spidergram/mindmap or ordered text or combination of suitable types. 2 content to include reference to at least THREE of: team - managers team - fitness team - same scores activities - swimming activities - fixed times, intro, lunch, prizes activities - to fit gaps activities - total times costs discount 1 reference to at least TWO of the above Q2 13 Summary of expected solution for Q2 Team selection meeting criteria; activity choices to complete timetable gaps; costs of activities and discount. team selection these marks may be awarded if answers seen in Q3 1 suitable teams of 5 employees including at least one manager 2 similar combined fitness level scores ie 16 and 17 matching team members individual scores individual scores do not have to be stated 1 combined level scores of 15 and 18 matching team members individual scores example Team A Team B Abbie (2) Alvin (3) Isaac (5) Lora (5) Ash (5) Shilen (4) Nita (2) Frank (2) Pete (2) Prita (3) Total fitness Total fitness 16 score score 17 activity choice these marks may be awarded if answers seen in Q3 4 3 additional activities chosen for the morning session AND 1 additional activity chosen for the afternoon session eg morning - fright wall, mud flume, power fan; afternoon - raft building 3 4 additional activities chosen that take 5 hours in total without morning and afternoon sessions identified 2 4 or 5 additional activities chosen that take 5 hours including activities not suitable for non-swimmers ie wipe out course and/or paddle boarding or 5 additional activities chosen taking 6 hours not including archery 1 additional activities chosen with one timing/calculation error eg incorrect time for one activity eg half hour or 15 minute gap left eg missing out lunch break eg incorrect totalling of times listed cost 2 correct total cost for their chosen activities AND archery eg for 3xA, 1xB and 1xC 1 correct total cost for their chosen activities without archery

4 or complete correct method, including archery, with one calculation error Note: correct method must include values in working shown 2 correct value for their total costs with 15% discount eg for correct value for 15% of their total cost eg for or method for 85% eg x0.85 seen or x eg their total cost total cost x0.15 check 2 no marks for repeat calc a complete correct check of any original calculation seen using a different method eg a reverse calculation OR a calculation using approximate values 1 a correct check which is not finished Q3 5 1 team members listed clearly within a structure suitable for a notice 1 timetable structure with rows and columns and appropriate delineation showing activities AND times with headings / labels for times and activities 1 given data ie intro, lunch and prizes clearly shown with times 2 all data entered for their activities AND times 1 their data entered with one error or omission Q4 1 1 suitable reason based on results or data given eg all activities are suitable for non-swimmers eg my combination (of activities) fills the morning and afternoon up Q5 3 3 three comments relevant to one or more review prompts ie plan and methods or sensible answers or difficulties or other information or tackling a similar problem some acceptable comments eg My plan worked in order so I picked activities and then I knew how much they cost eg My answer is sensible because is a reasonable amount for a training day eg I found it difficult to fit activities into exact time slots on my timetable eg It would be helpful to have the actual prices in the table (instead of A, B and C) eg Next time I wouldn t do anything differently because I had two teams with equal fitness and 5 activities that fit exactly 2 two comments 1 one comment some unacceptable comments eg My plan worked well. (ie unqualified) eg My methods worked well. (ie unqualified) eg My answers seemed sensible. (ie unqualified) eg I found 1B difficult.
