I have 25 days left for my GMAT exam and I find that my SC is pretty weak.
I've studied in an English medium school and college and I like to believe I am decent at the language. It would be great if someone could suggest how I can approach SC in these last few days that I have and improve my score. Thanks a ton!

If SC is the only ache, I guess you are on your way to success. With the vast resources on
this forum, Manhattan online practice and assessment, Manhattan SC guide (4th ed. or download previous version free)and the GMATPREP along with the videos on grockit.com, I think you have more than it takes to ace on SC. All you have to do is practise, take logs of errors, participate on forum and don't feel shy to ask questions;

Good luck.
