Just double checked that...and this is what the IDI's say...
"Occasionally, because of the nature of exam syllabuses, some students may be obliged to enrol on two or more part time courses; others may do so as a means of saving money on fees. Provided that the courses involve attendance at a single institution for a minimum of 15 hours of organised daytime study a week and the subjects are directly related, this is acceptable".
