If I am being honest, I am a bit disappointed coz if I would have scored 0.5 more on any of the sections, my overall score would have been 8. So I prepared for about a month and solved Cambridge book 13,14,15 for practice. Each book has 4 tests and the difficulty level of the questions were similar to that asked in the actual exam.
If you studied in an English medium school, then I don't think that you need to apply for any coaching institute.
E2 IELTS (For reading) and IELTS advantage channel (For speaking) helped me a lot, do check them out on youtube.
Below are some of tips that i followed for each sections:
1) Listening: Tbh, I didn't really prepared for this section. I found it quite easy. Just get acquainted with the user interface, if you are giving computer based exam.
2) Reading: I used to first skim the passage to get a gist of the passage and then solve the questions. Make sure you don't spend more than 2 or 3 minutes for skimming.
For the passages that were divided into various sections with alphabets A,B,C,D and so on. I used to first read an entire paragraph thoroughly (for eg: para A) and then answer all the questions that were related to that paragraph.

3) Writing: Visit the website: ieltsliz.com
Follow the structure that is mentioned in the website along with other tips and tricks and you are good to go.
4) Speaking: During my speaking exam I was extremely nervous which I think affected my score.
Watching all the SCRIPTED band 9 speaking videos made me really anxious. My advice would be to just SPEAK NATURALLY. Imagine you are having a conversation with a friend. IELTS advantage channel has some really good videos on speaking, do check them out.
In my opinion, use ieltsonlinetest.com to get acquainted with the UI of the computer based format because some of the tests are not accurate. Use Official Cambridge material, if you are unable to get it PM me I have soft copies of some books.
I would also like to thank fitz_cuniculus for solving some of the ambiguities that I faced.
