Hi whenlambo.
You could use the
TTP CR course in the way you suggested, first learning the basics and then practicing very carefully, and I recommend the following.
For each question type, make sure you totally get the strategy that appears toward the beginning of the chapter. The strategy may not seem that important, but it's actually super important to follow each of the steps in the order outlined. Also, practice applying that strategy untimed, and notice how each step supports your arriving at the correct answer to a question.
Use the Example and Chapter test questions in such a way as to maximize the value you get out of them. In other words, analyze each answer choice until you totally get why it's incorrect or correct. Getting the question correct is not sufficient. Only when you completely understand what's going on with each choice should you move on to the next question.
Shoot for accuracy around 90 percent on medium and 80 percent on hard because, to score 40+ on verbal, you have to get about 85 percent of medium and hard questions correct. Higher accuracy would be even better. Why get any wrong? If you get one wrong, figure out what you need to do to get such a question correct the next time.
Once you have done topic-focused practice on
TTP, you can continue to do topic-focused practice with official questions or start doing mixed practice. Be aware that many
OG questions are easier than any you'll see if you are scoring high on GMAT verbal.
