Hi - this is my first post. I have mind like a sieve and it doesn't matter how many courses I do, I can never remember everything I need to know. Are there any good manuals out there that can help my brain for VBA, DAX and M-language for Power Query? There are so many books out there and I really just need to help to for what function can do, so that I may reduce the time searching for the answers when I can't get it right.

Many thanks all in advance.
