[Amit Marwaha]

Hi there,
I have already appeared twice in IELTS and my last score was L8.5, R8, S7 and W6.5.
Is it better to apply for online module? as I have appeared previously in paper based examination. Is that will be good option to score better in writing section?
please suggest me so that i could upgrade my score.

thanks
