What I did is I used to go thru all the recent topics that were mentioned on IELTSLiz website. I had a story ready for each topic. I practiced all topics at home with 2 mins timeframe. If I also used Past-Present-Future technique.
I started my topic with like "Currently I like playing badminton (speak for it about 30-40 seconds)
then move to past but in my childhood, I used to play cricket( speak for more 30-40 seconds)
then switch to future however I have heard swimming is a nice sport and I can do it alone too.(then speak for 30-40 seconds).
Use firstly, Secondly, thirdly or finally for mentioning points.
Use words, like however, moreover, not only -but also, as well as.
Use paraphrases, I made a list of synonyms and I tried to use synonyms as much as possible.
Use In my opinion or It assumes to me or I guess or I think.
Also, check youtube videos of speaking. Prepare every topic and keep a story ready for every topic.
Prepare for section 1, as it will set an impression.
For section 3, first state your opinion then give an example.
Try to speak fluently.
Final tip: before going for an exam, check Ieltsliz's recent exam questions page and check if someone has posted a new topic which you have not prepared. Read about it online and prepare a story.
AB17 has given you some good advice. What I would add furthermore is that you should pay attention to the phrase structure, trying to build more complex sentences and presenting your ideas well organized. It is also important that for the subject on the 2nd part, you talk freely as much as possible in a natural flow. Try to search on BC's Youtube channel and others speaking samples. Good luck!
