I used to have the same problem.

Would you like to know how I learned to manage them all?

Stop studying them and yes get used to them with phrases, every time you read an article, a book or a lyric of a song you can learn more and more.

That works for me, of course that I will always have some doubts about them, that's natural, but at least I don't have to try to memorize them all.

I hope it helps.

You can learn it by youself with <a id="lleo_text" target="_blank" class="">English Grammar in Use. Raymond Murphy</a> for intermediate students.

That's the best book for grammar studying.

Hope it will help you.
