<p>tricky...
On the first one, i would say "she and I." Not sure of the specific rule (it may be idiomatic), but I know for a fact that no one in their right mind ever says "In order for I to make good grades." They say "In order for ME to make good grades."</p>
<p>On the second one (a little tougher), I would go with "I feel badly." Again, not sure why specifically, but it sounds terrible. Maybe "I feel bad" or "I feel strongly," but "badly" just doesn't seem to work.</p>
<p>are those the right answers?
I got a 760 on writing my first time (praying for an 800 on Oct. 4) and I never really prepped. I just use one, verrry helpful trick (well, helpful for me at least). I read the sentence out loud in my head multiple times. I imagine myself saying those words to a friend, and I see if it "sounds" correct. This bit me in the butt on 1 or 2 questions, because they were entirely rule-based, and sounded right either way. But for those Q's like your first example, sounding it out in your head, or even under your breath if you can, makes it more obvious.</p>
<p>I think it's "in order for her and me to be able to attend..." (which I know sounds awkward) but it's just like "in order for us to attend", where us, her and me are all objects of the preposition "for".</p>
<p>Not so sure about the other one, but I think it's "I feel bad about the conflict":</p>
<p>"I feel bad" = feeling emotionally bad or unhealthy
"I feel badly" = sensory perception in hands doesn't work (?)</p>
