Hi Nick,
As a belgian french-speaker, English is the third language I had to learn at school (that so small country has two native languages :-)). So I had the same worry.
Here are a few thoughts which helped me to get reassured :
It's not an english exam As Sun's customers are world-wide, they are used to read "poor-english" as ours. There is a french idiom which tells "Ce qui se con�oit bien s'�nonce clairement". Translated in poor english, it should give something like "Good design only needs simple words to get explained". Reading some threads here written by some native english-speakers (not all of them of course), I think sometimes that mastering english may be a handicap : they may explain in 200 words what we do in only 100, by lack of vocabulary. The only thing I am still afraid of is the
essay exam. I've been told that we cannot have any material with us at Prometric centers, I use an electronical french/english dictionary, and I still need it (for example, I had to search for 3 words in this
thread). As the main purpose of that exam is to make sure we are the guy who made the work, I think we should avoid any language level difference between the doc/choices and the essay.
Regards,
Philippe.
