RC roadblock-wont even move an inch----need help

Hi RC Expert..........................................

I was completely devastated by futile result of my RC. Since last 2 months every day I am doing RC(1/2/3 passage dependent on free time) ,but unfortunately I was stuck up with an accuracy in bet 50-60%. In few occasion more than it ,may be 90%, and in few occasion its even less. But most of time it is 50-60%. And the felony i did was taking 20-25 min for long passage.

I was reading NY times,Economist and few more almost every day. Still my result was same as it was 2 months back. I have gone through different strategy suggested in GMAT Club.But still no improvement other than i wont feel bore while doing RC.

I read somewhere in this club "Experiment with RC strategy" does magic,but long we will it take to get mastery?

Please help me to improve in both accuracy and timing. I badly want to see myself in improving trend.......
