Look at calendar for indication for this part of the

Award B1 for any indication e.g. start holiday on 15th

November.

FT for subtracting a month from ‘their 15th Nov’

15th October could be implied

FT for subtracting 3 weeks from ‘their 15th Oct’

If no marks gained SC1 for subtracting 3 weeks then

subtracting a month (25th October; 25th September)

OR for subtracting 4 weeks rather than a calendar

month (25th October; 27th September)

Reason could include reference to: 40 minute

turnaround at Moscow; outward flight code EP401

followed with return flight code EP402; first flight of

the day, etc

Be generous with this mark.

Condone reference to ‘Outward’ and ‘Inward’ above

timetables.

‘-4hrs’ might be implied by both times given as

London or Moscow times (gains second M1).

(look for 02:25(+1), 02:40(+1) )

FT ‘their 7hrs 45 min’

Could refer to needing to add 4 hours to the difference

(0 hours). Ignore further extraneous explanation.

FT for subtracting a month from ‘their 15th Nov’

If no marks gained SC1 for subtracting 3 weeks then

subtracting a month (25th October; 25th September)
