i have been studying consistently to get the concepts right and i was able to do that. for all 5 sections PS/DS/CR/SC/RC i was scoring above 85% and around 740-750 in my practice tests. i was planning to give gmat in a week or two. few days back, i got an order at the shop i work and was asked to complete it in 3 days. since work was too much for it to be completed in given time, i delved completely in the work and didn't even think about gmat for those 3 days.
since i have completed the work, i am feeling so low on my gmat ability. i can tell the strategy for each and every question on gmat but seem to have forgotten the rules for SC. my speed on RC to comprehend and my ability to quickly cut through the argument and pre-phrase an answer on CR seem to have eliminated. these questions seem to me as they used to be when i just began my preparation. when i do the questions i am making so many mistakes that i feel angry and shameful when i see them in review. i don't know what happened to me. please advise how can i regain my level.
