The most of high-school studients haven't planned their career when they graduate

The most of high-school studients haven't planned their career when they graduate. Why do they get into difficult or do someone affect their choices? I think, it is bad high-school educational system.

High-school educational system hasn't given not only career planning course, but also information of professions.

What's the purpose of this writing? It's not clear. What do you expect from others? Do you need help with editing you wrote or you need ideas to expand this essay?

.... or do someone affect their choices? .... what do you mean by this?

Hello, Dumi
Thank you for reply .
I'm just trying to write essay and It's my first time to use this site.
Now I m studying in iBT Toefl course. For me, it's very difficult - how to write essay in short time, how to issue idea and structure.

I need to write essay above topic, I will complete :p

Well.... follow the four para structure; Introduction, 2 body paras and Conclusion.
Introduction - Introduce the topic + state your opinion about the argument
Body para 1; Give your first reason for your opinion + support it with a specific example
Body para 2; Second reason + example
Conclusion; Sum up everything you said about and re-instate your opinion.
There are many good essays you find under TOEFL... Follow their structure :)
