My tutor doesn't take new students right now but I can give you some preparation tips, hope it will help you.
From my personal experience:
1. Practice, practice, and practice. There is no other way to prepare for IELTS, write as many essays as you can, listen to podcasts or specific IELTS preparation tasks, practice speaking with your tutor, read more professional articles in academic English.
2. Spend at least 1 hour a day to do something to prepare.
3. Don't forget about rest - I think this advice is the most important. There is nothing in the world that is more important than our health, so remember to sleep, eat, relax and spend time with friends)
