There's no problem! You will learn from mistakes eventually.

Hello GATAA RANA! I see that your edit is actually incorrect, and instead, it should be classified as a motorway link, not a trunk road. Trunk roads and motorways have a difference and there is a wiki for OpenStreetMap that explains this (osm.wiki). You can also press the "i" button at the feature type. Hope this helps!

Thanks again!

Hello!
I thought I couldn't tag that, so I just named it Public beach.
Thanks!

Hello, silversurfers83, I'll look into more detail at this!
