If you practise in general I think it will be not much fruitfull because we genarally use div span p some inputs tag ,some table tags ..etc.
So I suggest you to practice tags categories wise
For example practise all table tag in a project
Then practise all form tag in other project
Similarly for semantic tags,media tags ,table tags, text formatting tags,list tag , ,....
I think it will help to concentrate all tags in details.
And their use will be more clear to u
