I probably won't approach any problem looking for a specific error to begin with. Even though parallelism is the most popular SC topic (according to number of questions in the OG), I won't start every SC by looking for parallelism.
Similarly, I won't start looking for the structure of the sentence if the splits are visible very clearly just by scanning the answer choices. In practice, once you have solved the question, you can dismantle and spend time studying the structure. But on the test, you have to try and solve the easy questions in less than the average time so that you can spend those extra seconds gained on the medium to difficult questions.
When you are watching Ron's videos, one thing to bear in mind is that you already know the topic of the session. When he makes you practice the questions, you already know what to concentrate on. So be careful because in the real exam, this won't be the case. The takeaway from those sessions should be to understand the topic at hand and familiarize yourself with how its being tested. I am saying this because you seem to talk about the point of the sentence and the sentence structure and then idioms. He ran 3 sessions on the sentence structure and the point was to make you practice the type of questions that Stacey talks about in the second blog above. The point wasn't that you should approach every sentence correction problem in the same way.

This is news to me. Unless you and I differ in what we call "complete sentences", this comes as a surprise to me. So please elaborate more on what you mean by "complete sentences".

Short answer is no. No question on the test will ask you what an absolute phrase is. You need to know how a part of a sentence works. For example, when you see an -ing form after a comma, you need to understand what does it do in terms of meaning and grammar. But you don't need to know what its terminology is.
If you are spending a lot of time on the forums such as beatthegmat or gmatclub, then knowing terminology will help because forum users use it a lot to answer questions. But most instructors will not talk in terms of terminology unless its something very basic and trivial...such as a clause, a modifier, idiom etc.
rakeshd347 Wrote:Is it necessary to learn all the idioms and look for other stuff before looking at sentence structure.
If you have a good ear and can spot idioms as you read the sentence then that's a strength for you. MGMAT SC guide has a list of around 200 commonly tested idioms. I am planning on doing only these along with some others that I may have seen in the OG or GMATPrep. There is no exhaustive list of idioms in the English language or any language for that matter so personally, I will not spend crazy number of hours on it. I have studied English since I was 5 and I still have trouble spotting idioms as some of them have crept into our day to day spoken English. I don't think any amount of idiom study will prepare me 100% for what I will see on the GMAT.
Hope this helps, but please note this is just my opinion, not a rule.
