My apologies for the delay in replying Vivek and I hope my reply finds you well,
Anyhow, I am happy to attempt to answer your verbal questions in a moment. However, to you and anyone else out there who has been prepping for some time I would highly recommend sticking to the standard order of the exam. There is little benefit in changing an approach after having spent so much time preparing for a particular set of circumstances. I have advised each of my legacy tutoring students who were used to the AWA/IR/Quant/Verbal order to stick with that sequence and they have by and large seen solid results. I would suggest the same approach for anyone else who has been taking that format of PrepTest for their GMAT preparation to do the same.
As to general tips for your specific verbal approach:
SC- Focus on identifying the common errors of meaning and ignore the answers unless you cannot identify an error. The common errors you should focus on are subject-verb agreement, pronoun agreement, verb tense, parallelism, modification, and redundancy. Try to avoid evaluating idiom until you have adjudicated these errors as idiom is harder to parse. Working through the answer choices based on process of elimination is definitely advisable though.
CR- Try reading the question first. This will focus your reading of the prompts and speed up your per question time average. Then proceed to process of elimination.
RC- For the first pair of passages you should probably do some up front reading to understand the passage before getting to the questions. However for the final two passages it might be better to try and see if you can answer any specific detail questions without reading the entire passage first. It is all about maximizing efficiency here before getting to process of elimination.
As for timing a general recommendation per question is SC < 1:30; CR ~= 2:00; 1:30 < RC < 2:00. I hope this helps you as you prepare for your next attempt later this summer!
