Should you take notes in your native language or in English?

Today I had an interesting discussion with one of my TOEFL students.  He told me that he takes his notes, for the speaking section, in his native language.  He feels that when he has to read back from these notes he can better understand what he wrote - after he writes something in English he sometimes can't read his handwriting and he no longer remembers what he wrote.

What do you think of this approach?  I have always advised my students to write in English.  He feels that translating back from his native language to English is actually more comfortable for him.  I disagree.  People are always looking for 'tricks' or 'short-cuts' to 'pass' the TOEFL exam.  Fixing your English and speaking more fluently is always the best way to score high on this test.

If you have an opinion, feel free to comment or drop me a line at my e-mail above.  Thank you!
