Especially the listening part.I am a Chinese, and I concern that the listening part of TOEFL maybe the hardest part for most of Chinese. Anyone who has a great a idea to improve it efficiently?
I don’t think there’s any special or especially effective technique: Read a lot, listen a lot, compare the written part with the spoken one and learn vocabulary, both spelling and pronunciation.
The most fool-proof way to score high in TOEFL is to master the English language. I’m sure LingQ will help you in that endeavor.
