I really need point at least 6.0 What do you think how many score should I get ? :)
Well... I have not done IELTS so that I have no idea as to how much you can score here... But I can see you have good writing skills and you have enough potential to get your desired band, and may be even more.
This is the essay structure I recommend for this task;
INTRODUCTION; Introduce your topic to the reader and state your opinion
BODY PARA 1; Your first reason to hold that opinion + One specific example to support that opinion
BODY PARA 2: Your second reason + example
CONCLUSION; Sum up everything that you said above and reinstate your opinion.
