on a scale of 1 to 10 は「10段階評価」と言う意味です。
英語圏では100満点よりも10段階で表すことが多いです。
10段階評価だと細かい評価がでないように思うかもしれませんが、"8.5"のように小数点で表すことができますので実際は100段階評価と変わらず評価できます。小数点の読み方は8.5（エイト ポイント ファイブ）。「.」は「ポイント」と読みます。
ぜひ10を目指して学習に励んでくださいね！(^ ^)

What percentage would you rate my English speaking ability?
In the U.S., we usually ask to be rated on a scale from 1 to 10, with ten being the best.
But we also ask about percentages, which is technically a scale from 1 to 100. So you can ask to rated or judged on a scale from 1 to 10.
For example, "On a scale from 1 to 10, with ten being the best, how would you rate my English?
アメリカでは通常、「１to１０（１０が一番良い）の中でどのぐらいですか」と聞きますが、パーセンテージで聞くこともあり、その場合は「1 to 100（１から１００の中で）どれぐらか」という質問になります。
"On a scale from 1 to 10, with ten being the best, how would you rate my English?＝１から１０の点数で、１０が一番良いとして、私の英語力はどれぐらいですか？
By asking, “what grade did I get?”, you are asking how well you did out of 100, 100 being the best!
By asking “what would you rate my English?” You are asking for a number between 1 and 10, 10 being the absolute best!
All are often used in an academic setting.
what grade did I get?とは、100の内どのぐらい出来たかを聞いてます。100が満点です！
what would you rate my English?とは、1～10の数字を聞いていて、10が満点です！
全て、学術的な場でよく使われます。
What is my English proficiency level on a 100 point scale?
「私の英語100満点で言うと何点くらい？」は、
"What is my English proficiency level on a 100 point scale?"
です。
"proficiency"は、「技量、習熟」という意味です。
「100点満点で」は、"on a 100 point scale"です。
