Maybe this is the problem...
There are different ways in which the degrees and subdivisions of degrees can be expressed.
Google Earth, for example uses "ddº mm' ss.ss" i.e. degrees, minutes, seconds, and after the decimal point are the tenths and one hundredths of a second. This was what I was taught in geography at school.
Your Confuser example uses (d)ddmm.mm. In other words the degrees and whole numbers of minutes are given in one string without a break before the point, and after the point are the decimal fractions of a minute. So your example latitude N5207.62 E00057.47, translates to N 52º 07 min plus 0.62 of a minute which is about 37 sec.
I have put the d in brackets because longitudes are always given 3 digits since they can go up to 180º (latitudes only go up to plus or minus 90º).
So E 00057.47 translates to 0º 57' plus 0.47 of a minute or about 30 sec.
GPS receivers can be set to work in degrees plus decimals of a degree e.g. 57.7500 would be 57º plus 0.75 of 60 (minutes in a degree) or 45 minutes. Also east and west are given positive and negative values respectively as are north and south, so beware of this.
None of the Confuser examples you quoted was in my exam, it was a different route entirely.
I hope this helps.
Wishing you success in the exam.
