Hi Sana Shaikh, it depends . There aren't any strict rules. Be aware ,if you failed your test in 1st attempt , you will need at least 7 days to re-pass the test. Take your time, but also be wise with it. Don't postpone such an important things till last moment.

@ Sana Shaikh

You can do LiUK test whenver you want. Obviously you must do it before your application andf submit the test pass with your application.

But there are new requirements being introduced for ILR applications submitted on or after 28th October 2013.

When do you have to apply for ILR?
