Firstly, let me apologize for having misunderstood Alex... ehrm.. MRS. Viefhaus

photoread4me, I'm aware of the fact that there should be more specific purposes.

e.g. in history:
- My purpose is to understand why Hitler wanted to commit genocide
- My purpose is to understand which population groups he managed to influence more
- My purpose is to understand how Hitler finally came to power
- My purpose is to understand the foreign reactions to the nazi regime
- My purpose is to undersand the effects of the WW2 events today
- My purpose is to understand what benefits and negative aspects fascism has
or if you want something more practical:
- My purpose is to practically use this knowledge in my future work in social sciences

Hence, I should create many different purposes?

Or maybe should it be something like
- My purpose is to get an A+ in the history examination?

I sincerely have no clue on what you mean with a precise purpose for an examination.

- My purpose is to fully understand the whole context
is what seems more appropriate to an examination in which YOU DON'T KNOW BEFOREHAND what you will be examined about.

Questions in the last history exam were:
What are Charles Darwin's theories' responsibilities in the mid 20th century holocaust?
Could a better organization of the american economical plans in the 20s prevent the instauration of the nazi regime?
Have Stresemanns and Briands foreign policies efficiently contributed to the contemporary situation of Europe?
What are Germany's responsibilities in today's European Union and in general international relations?

Questions that are totally unexpected, yet have been hidden, less important-looking contents of the book.
