My time studying English

I have been studying English for 1 year and 6 months, all of this time I think that I have improved a lot but not as much I would like, I know that if I want to learn other languages I must study a lot and not only in my courses but also in my house or anywhere that I can. Recently I have been studying words that are easily confused such as arrive, get, reach, approach or like trip, tour journey and travel.

As far as I know is that, arrive can be used when we are specifying a time, for example: My plane arrived at 6:30 p.m.
Another use is when we are in a place, an airport for example, an airport but we are not inside of this place, that is that correct?

And we use "get" when we actually are inside of the place, correct?

[You could say "I arrived at the airport." or "I arrived at the airport at 6:30pm." or "I arrived at 6:30pm.". It doesn't necessarily mean a time, only that you reached your destination. You can also say "I got to the airport at 6:30pm.]
