Your lifters at “skool” don’t know what they are talking about.
Obvisouly you don’t realize that your shoulders (aka Deltoids) are hit during pushing and pulling exercises. When you bench, you are using your anterior deltoids (front shoulder), therefore, not much of a reason to do front raises, unless you are lagging there.
When you row, you are stimulating your rear delts, this is where many people are lacking, so doing an extra rear delt raise is a good idea, also face pulls are awesome.
Then on “shoulder day” you hit the medial delt, etc.
You obviously aren’t educated, and that’s why you are here. So instead of trying to develop your own thing (with lack of knowledge), why not use the search function and find a split that you like.
Also, did you know some people train their whole body at every session (ex. push/pull, total body training)?
Go read the beginners stickies and stick to one of those plans first.
