Badly need help to improve my SC. any1 could suggest tips

It sounds like you would benefit from some topic-focused review on Sentence Correction. You need to make the transition from understanding the concepts that are taught in the study guides to recognizing the errors on GMAT questions. If you've studied with the Manhattan GMAT SC book, you know that it contains lists of questions on the various topics (SV Agreement, Parallelism, Modifiers, etc.). Take one topic at a time and work out the related OG questions. Try to make connections between theses questions of the same topic and take notes on any key points you feel you need to consider for the topic (ie watch out for "and" on parallelism, and "wh" words are common noun modifiers). Work on a topic until you feel confident in your ability to recognize the issue and answer it correctly. Then move on to the next topic.

Once you get through a few topics, do some practice without knowing the topics that are being tested. As you eliminate answers on these problems, try to categorize your reason for elminating the choice. For example, you may use a SV Agreement issue to eliminate 2 answer choices, but the other 2 eliminations come from parallelism (you can't use "it didn't sound good" as a reason!!!). Check with the OG explanations to see how accurate you are in your practice. Spend plenty of time reviewing the explanation to see what things you got right and what things you missed.

If you see yourself struggling to recognize or correctly deal with a certain topic, you have to go back to your study materials until you get mastery.

It's a bit of a laborious process, but that's what the GMAT requires! I've worked with several people who have been very successful in improving their SC performance using this methodical, topic-based approach.

Thank q so much for your inputs.
Will try to work out your approach as well

Thank q ones again

I will add a slightly different take on the problem that you are facing. One of the key reasons that we see students struggle with Sentence Correction is because they don't have methodical approach to attack Sentence Correction problems. Somehow students have an impression that GMAT Sentence Correction is purely a test of grammar. Because of this understanding, students resort to a splits approach without focusing on the intended meaning of the original sentence.

We propose a slightly different approach - one that is centered around the intended meaning of the original sentence. Our students have had tremendous success with this approach. A number of our students have achieved accuracy improvements from 50% to 80%+ in their mocks using this approach and consequently have reported tremendous score improvements on the GMAT. We have 10+ application files in our course that help you follow this process and apply it to the easiest and the most challenging of problems. You can take our free trial to see if this approach makes sense.

Here are some success stories:
