I read MLIC notes, and I found them quite comprehensive. I have also gone through Manahattan SC. I have also created the
error log. So far what I have observed that during test, I forget to apply the SC rules or I do not apply them properly because of time pressure. I think main issue could be that I can not make the right picture of sentence in first reading and that leads to inability to analyse the sentence further. But if time permits I can read the same sentence again and again and can analyse the issue better. I find it hard to apply the rules mechanically.
I am not a native speaker. In addition, I did my studies in non english medium until 12th standard. I feel quite OK with quant as I can grasp information as I read the question ( by jotting key information). But when it comes to verbal, I find it difficult. I do not feel very confident about verbal, and when I come to something that I find little hard, I get a message that I am not doing it properly, or I can not do it with in stipulated time. As advised, I will start dedicating my time on WSJ and other suggested material to remove this -ve feeling.
I guess in my case solution is to gain the faith that I can perform well in verbal also, and few scenario that give boost to to this thinking.
