Hello Mr. Adi, my name is Aldy and my number is 1. Today lesson was quite fun and relatively easy. I'd like to improve my math and english more. I'm also thanking you because I had to use formulas from elementary, and that's a (quite) good thing to remember from elementary. The part that I liked is when we're making questions and answering others. Once again, thank you.

Hello I'm Nina absent 23. Today I study mathematics which I thought was difficult mathematics. And my opinion about mathematics today is very useful. It turns out that after learning it in English I am easier to understand. Math scores have increased slightly from the previous one. And now I think that mathematics is not as difficult as I imagined. Thank you, Pak Adi for your tutoring, I am very easy to understand. Thank you for uploading this material too!

Hello Mr Adi, this is scott from efmasa number 2, and IM here to tell you about the evaluation today and the five names that I found.
1. Dimas
2. Izzat
3. Aldy
4. Hafiz
5. Arya

Today during efmasa, I had a good day because I could speak English With my friends especially discussing about mathematics in English about area and perimeter. Before, the style of teaching about mathematics was fun and interesting to because we had a chance to do some group work together and this time, almost all the students went in, so its not boring. I think that the only thing that I can say about today
