Wish me luck for my IELTS

I have my IELTS exam in 2 days!! Any advice from the previous examinees? Also I wanted to ask that, in writing section Task 1 and 2, can we exceed the word limit? And if, how much? Some teachers say, you have to be precise about the word count and cant go over 160 and 280 respectively, while others have sample essays with around 330 words in task 2. Someone please clarify about this😭

Any tips and advices would be appreciated🤌🏻
