Sentence correction !!!

i have been practising for the last few month, tried materials from various sources, veritas prep and MGMAT. i found MGMAT pretty helpful when it came to SC but i thought eGmat did a better job breaking down each sentence and explaining what role each word plays in that. i would definitely say it has helped me not only understand SC better but also helped solve the problems quicker.

overall my GMAT score wasn't great (680, Q47, V36), it was the math section that dissapointed me. i was actually happy with my verbal score, it was the same as the best score i had on the practice exams. hopefully with better preparation i can crack the 700 ceiling

the one thing i regret not doing is completing each section of SC in eGMAT, i was running short on time. this time i have 3 weeks to prepare and hopefully i can do a better job
