ACMS..is right. There are a lot of places where the ground controller asks to monitor tower freq. Its not an instruction to call tower. We'll just have to listen out and tower ctl will call when he/she is ready. Usually happens in UK/US.
About the "english" test, i guess it depends on whether its the english or american version. Heard it can be quite tough, most guys got level 4 or 5. Well better start taking some english tuition!
