bu ielts課程ok嗎?

Yes, if your English is above intermediate level , I suggest you do the mock paper first. But I wanna remind you that the IELTS mock papers from Mainland China are quite easy in listening paper. Therefore, you can only do other parts of the mock paper, they are up-to-standard~
If your English is not that good, then you should take some courses to upgrade your English ability first~^^~Good luck.

其實....IELTS 不一定要報讀的...
我考IELTS 都冇讀過任何COURSE, 出黎既成績都吾錯...
買本書睇下都得架LA~一定要做勁多PAST PAPER!!!(圖書館有得借)
想買又平又OK 既IELTS 參考書, 去深圳都係個吾錯既選擇!!
因為IELTS 係全世界都有得考既試, 大陸IELTS 書都吾係好差...
起碼冇香港賣既台灣 IELTS 書咁 "浸"!!
