Before you decide on a tutor to help you study, please take the following precaution:
1)Always ask for a 60 minute trial lesson.
It takes a good teacher that long to assess all of your
current skills accurately.
2)Ask to see the tutor’s credentials(diploma, certificate etc.)
If they cannot, or will not provide you with this
information, don’t give them your money. They likely will not
have anything of value to offer you.

Thank you for your warning and advice too. I believe you are also tutoring Japanese students in Englsih. How much is your tuition fee if I ask you to teach me coversational techniques?

I am now going to undergraduate school in Vancouver, and I think I am OK with writing and reading, but not speaking. It may be because of a lack of confidence. I tend to speak less and sound awkward when I talk with native English speakers, or I maybe too self-conscious.

If you don’t mind, please post your ad here again. Thanks. 　

Why are you posting this? You should concentrate on getting students instead of slagging other teachers. Plus, a 60min trial is unusual. Usually, it is 30min. 　

To Res. 2:
caveat emptor 　

Brilliant. Obscure latin sayings... 　

To Res.4 who is also Res.2:
This Latin phrase is a very common and taught in any highschool commerce class, and therefore not obscure whatsoever. Since it means ’buyer beware’, this phrase is completely apropos in the context in which I used it.
Furthermore, it is readily apparent that your cowardice in remaining anonymous is a direct result of your educational insufficiency. 　

To Hans/GO-EIGO EDUCATION

Who do you think you are? You are just one of the English language teachers, which isn’t a special occupation at all. This site is for Japanese people, you should get out of here. Are you in that red that you have to try so hard to get Japanese students? You are acting as if you are such a nice person, but actually, you are just annoying. No one is impressed by all your wordy explanations. 　

By the way, I (Res.6) am neither Res.2 nor Res.4. 　

Dear Hans/GO-EIGO EDUCATION,
I’m not res7, but I’ve seen your ads and comments here
for some time, and I have to say that you have a very
cynical and snobbish way of dealing with people. Trully
smart and gentle people don’t get so defensive as you
do. Good teachers usually are patient and caring. I have
to say you’re ruining your reputation by advertizing here.
　

Don’t believe a piece of paper. 　

Mr./Mrs. Res.9

What do you mean?
Is "Don’t believe a piece of paper." a kind of expression?
I just have a curiosity to know the meaning!
I’ll be really glad if someone teaches me! 　

He’s talking about printed credentials (diploma, certificate etc.). 　

Oh, I see!
Thank you for teaching me!
