I copied it from an app I installed from Google Play, helped a lot with learning. I couldn't get the code straight while typing so I had to write in English in order to get it how it is. You can download it if you want.
For android/ios you can use GGMorse app by your own - https://play.google.com/store/apps/details?id=com.ggerganov.GGMorse&hl=ru&gl=US&pli=1
It looks like an impressionist version of a radio like this:

Watch a video so you can better memorize the sounds of each letter. Deciphering/reading morse code is way harder than spelling.

I also advise you to use a morse code app to practice spelling. I myself use this one:

My opinion on the app:
It's not perfect though. The frequency of the letters you have to spell in morse code is determined by how frequently they're used in everyday life, instead of each letter popping up the same amount of times. So you get to practice x/y/z less frequently as e/r/w for example. But except for that, the app's got everything you need.
I'm horrible at receiving morse visually, it'd be so much easier for me if it was audio, but unfortunately that's not how they put it in the game.
I did a ton of those in the past when battlefield 4 first came out, and I know that it eventually gets to a series of numbers, but your video didn't have that part. Also, I heard that it has to be done in one session, so if you closed the game after your recording, the numbers could be different the next time you go in.
I suggest this app on your phone to decode it reliably. https://play.google.com/store/apps/details?id=com.blueta.morsetransmitter

You can look up exam sessions near you and I think you can look up local amateur radio clubs, too. Just show up for a meeting, usually nice guys and gals, mostly guys.
This is the book that helped me study for my first exam: https://www.amazon.com/Now-Youre-Talking-First-License/dp/0872597970
