I got less nervous with each attendance to the lesson.
As I attend to the lesson, I got less nervous.
1. 「緊張」は、「nervous」と言います。「I am nervous」だと「私は緊張している」となりますが、「I get nervous」だと、「私は緊張する」になります。ですのでまず、こちらの文章では、「I got less nervous」「私は、以前より少量の緊張をした」、つまり「緊張が少なくなった」とします。そして、そのあとの「with each attendance to the lesson」は、「with each A」で「Aをするごとに」という意味のイディオムを使っています。こちらのAに入る単語は「attendance」という「出席」の意味の単語です。
2. こちらの文章は、「As」を使った文章です。「As」を使うことで、「〜するごとに」という表現が可能になります。こちらでも、１で使用した「attendance」の動詞である「attend」を使います。先ほどの文章では、「レッスンの回を重ねるごとに」という文章が文の後半に来ていましたが、こちらでは日本語と同じように文の前半に持って来ました。
The more lessons I took, the more confident I became.

So, you may say:
The more lessons I took, the more confident I became.
or
As I took on more lessons, the less nervous I became.
or
The more lessons I took, the less nervous I became.

When we first meet someone or learn something new, we can feel a sense of nervousness and excitement. As we become accustomed to the new situation and as our skills develop the feelings of nervousness become less. This is a growth in your confidence and skill set. As a teacher this is a wonderful thing to see develop in your student.
As a student the feeling of confidence is brilliant and allows the creation of new adventures and learning.
