hello help pls I don't know how to study and after one day there is my oral test and I don't no even know single word any tips?

Try reading the main points of the chapters.  

Explanation:

If you have notes, reread them. ( If one has notes, I am sure they will write down the main points in it. ) If you have little notes, then try remembering the questions your teacher mostly ask. They usually add these kinds of questions in exams. The test is very close so, the rest depends on you and your skill.

Nevertheless, I wish you the best of luck.

nothing. let it run its course
