Hi I just want to ask if when do i need to take a test for KNOWLEDGE OF LANGUAGE , how much it will cost me? And also about Life in the UK test? how much it is?

Are the Uk Border will send me an email to say when i should take a test of KOL?

I try the free test and i got WRITING: 77/85
READING: 150/250
LISTENING:160/250

IS THIS A GOOD RESULT OR NOT? I CANNOT TRY THE LAST TEST.

AND WHAT IS THE ESOL MEANS?

APPRICIATE ANY IDEA THANK YOU!
