Hi Yashi,
Good try indeed! For writing please go through Liz's classes. Its very useful.
Listening also she gives gud tips. Speaking go through the videos in youtube and tips by liz and rebecca. Reading its better to write the full abbrevation( for true or false & Not given) next time dont take a chance. And better give ur next try with IDP. Seems the scores are quite favourable than BC.
My best wishes for ur next test. All the very best. Take care!
