Nice dialogue! Very well done.

Saki, if you want to make how to end the conversation simpler, you can say something like, have a nice day and talk later! or something like that!

I liked the scenario you guys created. Hirotaro, it wouldn't hurt if you request a pick up a bit politer. You can say something like, would it be possible for you to pick me up at 2 to go to my lawyer, as I cannot drive now. You can even start by saying, I was just wondering if you can blah blah...

At any rate, very nice job, you guys! Well done.

Nice. In this scenario, Takumi and Ayako must be best friends right? So it is intended for the dialogue to be casual. At first, I thought Takumi said you want to go to France tomorrow! But you said for lunch tomorrow, right? :)

I liked the fact you smiled a lot and seemed happy in this conversation!

Sakutaro and Marina, Good job!

I like the usage of 'actually' in conversation. I liked Marina's friendly response, too.

But I had a bit of difficulty hearing your conversation since it was so noisy in the background. Can you go to somewhere a bit quieter next time? Thanks.

Hi Naru and Nen

Very nicely done! I liked the expression 'couldn't be better' by Naru, in his response to Nen's 'and you?' question. It seems you two know each other very well in this scenario and that's why you didn't even need to say who you are when you called?

Keep it up!

OK, so first Masashi left a message on Hinami's phone. Then Hinami called Masashi back, and this time Masashi was there to pick up the call? The first one is OK as it is one way call, but the second one could have been a bit more interactive (Masashi could respond with 'yeah, I did (call), can you please let me know how I can prepare?' or something like that. Otherwise, I think both of your English is good, and meaning got across! Good job.

I could tell you guys a bit nervous (as Risa and Kozuki had nice big smiles when the recording finished!) during the dialogue. I liked the fact you extended the conversation by Kozuki's asking Risa to help him with the test prep. 'Teach' is OK but 'help' could also be good when you ask for help to study. You can say something like, 'I am not 100% sure about the contents, so do you mind helping me prepare for the test?' ぐらいがいいかもしれませんね。Very very nice job though! I liked.

Koetsu and Ako, nice job!

Koetsu said can you have a lawyer request? (sorry it was difficult for me to hear it but it sounded like that) You can simply said, 'Would you need a lawyer?' as that sounds more authentic. Ako said where will we meet? It is a tongue twister, eh? (言いにくいですよね！）So you can say, 'where are we going to meet? ' or 'where shall I meet you?' if they are easier to say, as basically they all pretty much mean the same. Everything was natural and the dialogue was good.:)
