Sentence structure

I just took an N3 jlpt test which I probably failed, but the most infuriating thing is that I couldn’t for the love of god (in the test nor before) fill up the sentence in that part where you fill words to complete a sentence and choose the one where the star is. I really suck at this, even more than with listening which I thought would be much worse.

So my question is, are there any sites only with those types of questions where I can practice this?
