I had completed the OG11 a couple of months ago and now working with the OG10. I knew my weakness is on SC so I am working on the SC questions for the first time in the OG10. I am using the worksheet to mark down my errors and doing 40 at a time. However after 200 questions, my score has always been around 25/40. I can't seems to improve. When I read a question sometimes I am still not able to pick out what is wrong in the original sentence at the first read.
Any tips?
