For the oral exam the typical difficulty is to do it fluently and with few mistakes. Let's focus on the main problems:
- fluentcy and entonation: try to say full sentences and mark a rhythm in your performance; don't rush, say a couple of sentences qhen you speak and try to sound natural
- accuracy and avoiding mistakes: learn some structures which are useful, mind tenses and use a good vocabulary, especially with the topics of the book
To practise on your own, use your mobile to record your performance, especially the individual part, and try to practise with other students by Skype or by phone.
Reading is not very difficult but if you wnat to practise with cloze tests you can go to this link and this one for multiple choice for intermediate level. Forn higher levels, you can use this other link by choosing advance level. For advanced level, you can use this other link as well.
