The best teacher ever

Today I have taken two online English lessons. It is more natural to say: "Today I had two online English lessons."
At During the first lesson, I was so/very nervous.
But at during the second lesson I was relaxed and the lesson was fun.
The second teacher always smiled and her attitude was tolerance she had a patient and positive attitude (or just "she was patient").
She encouraged me to talk in English and gave me enough [or "plenty of"] time to speak and as she listened patiently.

理想の先生

今日はオンライン英会話をふたつ受けました。
最初のレッスンは、ひどく緊張しました。
けれど２回目のレッスンは、リラックスして受けることができ、レッスンは楽しかったです。
２回目の先生は、レッスンの初めから終わりまで笑顔で、寛容的な態度でした。
私が話す時間を十分に取って話す事を促してくれ、辛抱強く聞いてくれました。

I'm glad you had a good experience with the tutor, Momo :)
