Charles, Manish, and Ajitesh - Thank you for your feedback.
Here're some more insights on my test performance. As rightly pointed by
GMATNinja, I spend too much time on the last two answer choices, trying to find out such minor differences as idiomatic usage, preposition usage, change in meaning, among other things. I am able to read and understand the sentence, perform elimination, etc. well within 60-75 seconds. However, I become extra conscious while picking the final answer, resulting in spending 2+ min of SC questions.
Surprisingly, SC is my strongest area and have consistently scored in 45-50 range on GMAT Prep and other practice tests. However, I became extra careful during the actual exam so that I do not miss a single SC in the first 1-20 questions.
