Triad Chord Analysis

Just completed the triad analysis worksheet, first ten I had to write out the notes to work backwards, and the last ten I did in my head but it did take a while. I think it is slowly sinking in but is taking me a while. I guess it’s just doing this stuff over and over that will make things quicker.
I understand the theory of it all but just takes me some time to go through the ttsttts thing to get it.
I am wondering if it would be best to do some more of these exercises before moving on to inversions and jumbled triads,
