Is it Beginner's level or Beginner level?

Hi teachers,

I am writing an email to my best friend, Jan, who lives in Australia.
These are some of the things that I am going to tell her in the email:
…
There will be no school for a few days on 18th this month due to federal holiday.
I am thinking of doing some self-paced learning at beginner’s level, such as Japanese, painting, horse riding.
…

But I am not sure if I should say Beginner’s level or Beginner level.
Compare: Intermediate level, Advanced level
Are there any other grammatical mistakes in my email, teachers?

Thank you.

Kitty.

At beginner level would be fine.

A minor addition -
“…no school for a few days BEGINNING on THE 18th OF…”
You can’t have a few days off during the one day, so it is a few days starting then.

Well, Jim in above statement you said: “…no school for a few days BEGINNING on THE 18th OF…”

When to use and not to use “of” after date(is it applicable only with numericals?). Please explain it grammatically.

As you know, when it’s your native language, you don’t always know the “why.”

It’s NOT the number, I would also say, “The first of the month…” and so on.
As I look at the sentence, the meaning is really, “The first DAY of the month…” but we leave out the word “day” and keep the rest of it.

Hope that helps
