Me unrealistic?

Was rummaging through my stuff to be thrown away during the massive spring-cleaning exercise at home and chanced upon this psychometric assessment exercise i did during JC. Apart from shedding some light about my aptitudes [very high ability in general reasoning compared to peers (yay!), very good critical reasoning skills with written materials (yay!), good numerical reasoning skills (ok, i concede my maths is shit!)], my vocational interest scores were also tabulated as below:

Realistic = 10
Social = 38
Investigative = 21
Enterprising = 37
Artistic = 30
Conventional = 20

People are classified into the 6 broad interest types as set out above by Dr John Holland in 1971. I wonder how true or relevant the result of this exercise is now, given that it was done so many years back. Anyway, read it with a pinch of salt :P
