I suggest the best thing one can do is make a study plan and stick to it. I would recommend you to take several important steps.Find out whether you need IELTS Academic or General TrainingFind out what band score you need for your visaTake a practice test to find out what your current English level is in terms of the IELTS scaleThen familiarise yourself with the test format, task types and assessment criteria. There are plenty of online resources where you’ll find useful tips. For example,Quora (you can easily find the most viewed writers in the categories connected with IELTS and IELTS preparation)ielts-simon.comhttp://ielts-liz.comhttps://www.ieltsidpindia.com/information/ielts-preparationhttp://ielts-mentor.com (a lot of good reading passages)IELTS Speaking Assistant | Facebook (IELTS vocabulary and several articles dedicated to writing; BTW written by me)5. Start doing IELTS practice tests. If you have plenty of time (at least 2 months), I would recommend you to start with the aspect you are weak at. Thus, you’ll have more time to improve your skills. First, do only listening for 2 or 3 weeks, then writing. After that practise IELTS reading for several more weeks. The thing is that your skills develop faster when you do the same activity for a long time. When the exam date is nigh, start doing full tests.LISTENING
