Improving sentences MAJOR problem (FOGCITY!!)

<p>I know all my grammar rules, but I am still getting lots of answers wrong. I have know idea what the problem is.
Also I seem to be having issues with the improving paragraphs section
Does anyone have any advice?</p>

<p>Try to see if your issue is “careless mistakes”. Also be sure that when you improve a paragraph, you don’t change (or minimize the change to) a paragraph’s message.</p>

<p>Also try to see if your issue is with idioms. Eg. Not only…but also, between x and y, neither x nor y… and not: not only…but, between x to y, neither x or y</p>

<p>Thanks mate, I think it could be careless mistakes to be honest. Looking back on my tests it seems that I am choosing answer choices which fix the mistake in the question but have a new error e.g. comma splice. I should be fine.
As for improving paragraphs ill just keep sticking at it. Everything is just frustrating me at the moment.</p>
