Hi Sheila,
Many GMATers find SC to be challenging - so you are not alone. SCs are 'technical' in nature (similar to how Geometry questions require knowledge of formulas), so you need to know the grammar/idiom rules really well (and be able to spot when they apply) to score higher in this category.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
