Less than one week to prepare for the exam ! All the very best to everyone ! As I see it, N5 is a little bit easier than the old L4 and N4 has a mixture of some L4 and L3 grammar structures. The changes in format are also minimal. Paper 2 (Grammar-Reading) has the new 'word-arranging' item to find out what the 'star' slot is. I find that fun ! I am sure less people will be falling asleep this year, during the exam. :)
I also find the Q&A section in Paper 3 - Listening, refreshing and quite interesting. This can really test if you are familiar with the usage of common expressions and phrases.
