What's the hardest section of the TEOFL test?
I think the writing part might be the most challenging party of the TOEFL test. Listening and speaking have their own challenges, but with at least a basic understanding of English, those sections are easy to pass. The writing section instead requires a better understanding of English, especially of its grammar and sentence structure. Also spelling can become quite challenging.

What's the hardest aspect of learning a foreign language?
As someone that had to learn English as a second language, i can say that the hardest aspect of learning a new language is the constant need to compare what we learn to what we already know in our own native language. To learn a new language in the best way, we have to stop making this comparison and learn this new language as a subject of its own, just like we would do as if we were learning Music or Math.
