Welcome back from a long summer holiday! I hope you had a lot of fun and you are now ready for new challenges!

 

 

Let’s start with something interesting:

 

 

I haven’t got a clue about it! I have no idea about it.

I know it like the back of my hand. ⇒ I know it really well.download

It’s common knowledge.Everybody knows it.

I’m learning the ropes. Learning basic details of a particular job

My English is a bit rusty.It needs improving

It’s second nature to me at the moment.I know it really well.
