suzanne, others~take tse or the new toefl-ibt?

hi everyone....this is for my roommate.

she has been in US for three years, petitioned by current employer and on a working visa. has the CGFNS certificate, passed the NCLEX-RN, and now is trying to get her documents collected for VisaScreen. However, she is having difficulty passing the TSE. She scores 45, and needs a 50.

She has tried workbooks, she watches a ton of american tv, and she speaks only english here at the house and at work. very rarely she speaks her own language anymore, usually just when talking to her mom back in the philippines or to her couple of friends here.

she does not understand the new toefl which contains the speaking part. is this supposed to replace the tse? she has completed everything else but the speaking portion. i was wondering if someone can explain the new test to me (us) since she reads over my shoulder...lol. i'm trying to get her used to my computer but she's a little shy in that regard. she read that the new toefl ibt was easier to pass than the old tse, so she wants to try it.

thanks to anyone who can help.

p.s. and can anyone share your secrets for tackling this tse? other than doing what she's already done in regards to speaking only english, etc.
