After reading these posts, I must say it is interesting how some people can draw conclusions conveniently without even getting hold of any substantial information.
Can the school be a possible factor leading to her suicide? Yes, highly possible but it should not be seen as the only factor. There will definitely be students in the school who are doing the same modules as herself. Does that mean she isn't as smart? Well, maybe. But do bear in mind at the end of the day, suicide is a personal choice. Even if we do assume that it could most probably be her inability to cope with school, the main reason will be more direct causes (mostly psychological), such as her fear of facing her family, or dreading what her future might hold.
No matter the reason, whatever we can discuss here will be non-conclusive and remain as a hypothesis until there is some form of substantial information to get hold of.
On the side note, in regards to the comments about our rigid education system, I won't deny that it is definitely modelled according to how the economy is doing. However, before we start pointing fingers, we should step back and think why our government does it. Firstly, we don't have a large land mass, no secret by now. That leads to very major limitations in terms of how we can expand physically. Secondly, we don't have any natural resources so to speak of, and obviously you know what that leads to. Our education system, is essentially the source of our country's bowl of rice, and hence the need for its revisions according to the state of the world.
It's always easy to blame or criticise a certain system, but finding solutions are a lot harder. Even the best solutions will bring up new problems. Think about it.
