For a good revision of the structures you're going through in the next exam I've posted some interesting websites you can go to. In this webs you'll have exercises of Future with WILL & GOING TO and other sites with FIRST & SECOND CONDITIONALS, and both mixed for practicing recognition. I highly recommend practicing these exercises. GOOD LUCK!!
