Ipick up NCE4 as my learning materials as it has original reading. It is the main reason I would like to use NCE4.
I could improve my writing skills after I read every lesson many times. In addition to that, it is a famous learning material which could save me a lot of time in studying.
One of shortcomings of NCE4 is that it has the British English rules and expressions and it is not updated, but it is not a big deal as nothing is perfect.
I like its depth and length of each lesson.
I just want to focus on what I would like to obtain from it.
