Hi Lorena,
To improve in SC, one needs to work on the core skills:
Sentence Structure in Sentence Correction. We recommend a Meaning based approach to solve the SC questions so that you never get confused between two answer choices even when both seem to be grammatically correct.
EGMAT’s Strategy for SC1. Read the entire sentence
2. Understand the meaning
3. Look for mistakes in the original sentence
4. Check the answer choices.
5. Use POE (Process Of Elimination) to get to the answer.
To understand more on this, i suggest you go through the recording of the recently held SC webinar
here. The following are discussed in the webinar:
•
Importance of Meaning - How to leverage meaning to solve 700+ level SC questions.
•
Gain 90% accuracy - How to develop a systematic process for solving any SC question.
•
Improve your Sentence Correction Ability - How focusing on meaning can improve your SC solving ability and can make you cross the V40 barrier.
Hope this helps.
