how does ielts listening paper mark?

[tyezaa]

To be very frank,i have been very tensed since i gave the ielts exam.That was on 5th of june.It was listening paper that i made many silly mistakes.Actually i was study on my own for this exam ,so i hardly get any advice.The mistakes are about plural words and ajective, such as the words"shared room and insects".I would like to know that whether i would be penalised a lot or not if i made these mistakes.Due to this reason,all the rest was ruined and i couldnt do my best.Imagine i was speechless infront of the examiner during the interview.Hopefully, there'll be someone who can help me out!!:-|
