Attended various 'hobby' TAFE Courses years' ago. Much enjoyed.
I consider my various work/career Courses equivalent to TAFE.
These were many, prob nearly 400 over 45 years', ranging from easy to extremely difficult.
I was fortunate in that the main ones' I studied, whose Pass mark was always min 85%, I passed with 'Honours', & I was usually class 'Dux'.
It helped in that I loved my work, & never found it a difficulty at any time.
