what's up with form 6?

I'm just really curious as to why people say Form 6 is tough and not a good a choice at times. I can't possibly know first-hand because I didn't go that way so I got my friend, Joann, to write about it.

Joann and I met during a workshop for Malaysian teens called 'Ideal Teen' 4 years ago. We've not met after that but still kept in touch until today. This is what she had to say:

Form 6 is tough for me as we have a lot to study but a limited time.so, time management is very very important.just a slip of mistake, u'll need a long time to correct it. things like extra curriculum, tuitions, assignments, projects, practical experiments, .. all of this is the thing that cause you to have 'Not enough time syndrome'.especially for those who are holding high post in some society such as librarian board, perfectorial board, etcThose who can't manage themselves well, will face 'Depressing syndrome' and their academic result will fall off.Its pretty hard to manage everything in time.You just can't expect things to go on well in your way.for example, u can't expect to have a teacher who teaches you everything tat is written in the syllabus, you have to do it yourself. if we're lucky enough, we get really good teachers. if not, that subject is all your own to manage. This is why people say form6 is tough.

So, what's up with Form 6? You tell me. Would love to hear.
