Your title says "OG Review" so I assume that you're referring to one of the OG books, probably the 11th edition (orange book). Unfortunately, we are not allowed to post specific OG problems and explanations on the web. The company has exercised its copyright privilege and does not give anyone permission to post OG problems or explanations anywhere online.
I don't have my book available right now but generally speaking problems in the 230 range in OG11 should be 700+. The book authors do say that the problems are in order of difficulty, though I have also been skeptical at times re: the placement of certain problems. I have no reason to doubt them however - and I know that it's very easy for us to think a certain problem is easy or hard (and it is, for us) when it's the opposite for the general population. Difficulty levels are based on the general population, of course, not just me, and my personal opinion reflects my own strengths and weaknesses. In other words, it's really hard to gauge the difficulty level of a problem.
If your class is still going on, you can ask for OG explanations during your office hours, or before or after class. You can also search the archives here to see if the problems were posted before the OG online ban went into effect - the pre-ban archives are still available.
