I totally agree with KIYOsan's idea. It's a very idea
that English learners use TOEIC materials when starting studying English.
I recommend they set a time limit for using the materials
if they really want to improve their English skills.
However, I don't care whether Heavy TOEICkers do only TOEIC training or not.
I don't understand why TOEIC haters mind TOEICkers behaviors so much.
Can't TOEIC haters leave TOEICkers in peace??
