Im going to take the 231 on Monday night and 232 on Tuesday night... I see that comptia grades from 100-900 with a minimum of 460ish to pass. Does that mean I only need to get half right, or do some of the questions continue to have more "weight" than others depending on the difficulty of the question?

"The minimum passing scores for the A+ linear exams covering the 2001 objectives are 467 for the Core Hardware exam and 469 for the Operating System Technologies exam. Both exams are graded on a scale of 100 – 900"
