Hi there,
First of all, my recommendation is "Don't be upset!!! Keep practicing!!!".
Here are couple of more advice for you:
1. Reading: the most two difficult and time consuming questions in IELTS, as I think, are Matching titles with paragraphs and Matching summaries with paragraph. My experience is to leave these at last. Firstly, you should try to do others questions that considerably are easier than above ones. Then, the tricks for these difficult questions are to read the first sentence, couple of last sentences of each paragraph which include the topic and the conclusion. With this you are able to pick up some correct titles to link to paragraphs. After that, if there still are titles/ summaries to select, you will need to quickly read carefully the paragraphs one by one. I am sure with this techniques, you will be able to fully answer these toughest categories of questions.
2. Listening the trick here is practicing the practice test from books, such as from Cambridge, McMillan... the more practice test you do, the higher possibility you gain high score. This familiarises your ear to react to the Ielts conversations. It also helps you to get used to the pressure of the listening section. In addition, pay attention to the ending sounds of nouns since it is really difficult to notice them if you don't concentrate enough. Last but not least, try to read the questions in advance to prepare yourself with sufficient information and what kind of questions are next.
3. Speaking: this is my own trick, in case you are anxious, you may drink a half bottle of volka/ spy or any alcohol (200ml) an hour prior to the speaking section. I've tried and it paid off
. Nevertheless, most importantly, you have to practice speaking in a organized way.
