What made me angry is no one ever told me that I have grammar problems. I thought my grammar is perfect so far. As I read my old essays, I realized that my teachers tolerated (or didn't notice) my mistakes. I wonder how did they read a shit full of grammar mistakes, and only commenting "good job, but word count is a bit less"...
I've always dreamed of reaching a band 7 in writing. Always wondered why I'm stuck in 6.5. And doubt myself that it's my ideas to blame. I delayed to analyze my essays and to work on my writing deeply, and now I'm paying off.
