The executive summary is basically a summary of what you talked about in your report... hope it helps because i don't know what you wrote in the report...
just some added information if you didn't know already is to underline all your headings...
I think it is more of how u use your time not how long... also one of the keys to helping you in your studies is to actually listen to the teacher... they tell you a lot of thing that are quite helpful... of course depending on the teacher...
the reason im thinking of dropping music is because i find it boring and also partially because of the teacher... i know that sounds sad but like yoakim i enjoy it more not as a subject... well anyway i have to see how well i do in the practical part...
Interesting... For music i got 87% but that is only from one exam... as for needing music in my tertiary study i dont really plan to do something in the music industry.
prelim is different. but at least you can actually choose subjects you like well except english. i suppose it is something that has to be part of our lives... though i have to say learning other languages are fun! =P
