Question 4

Hi @Yemisi, Thanks for the question! So here, the question is asking us how many of his grades can be determined. In other words, we have the six courses, economics, geology, etc. We want to know how many of them can we know the grade for sure. For example, if we can say “he got an A in Italian,” then we have DETERMINED the grade for that course. And that’s what the question is asking for; there can’t be any doubt as to what the grade is assigned to the course for it to be determined. We can’t have G and P in grade A based on both rules 1 and 4. John can’t get an A in both G and P, since he has to get a higher grade in G than P (and an “A” is not higher than an “A,” they’re the same grade). Also, if both the grades are A’s, then they aren’t consecutive (like AB or BC), which violates rule 1. So that’s why John can’t get A’s in both 1 and 4. Hope this helps! Feel free to ask any other questions that you might have.

I completed the game set up to a T, and had everything figured out, however, in the rule it says Russian and Italian must be consecutive and Two letter grades are consecutive if and only if they are adjacent in the alphabet. With that said, I don't understand because the letter R is not adjacent to H and Russian and Italian have to be consecutive and John got a better grade in history than in Italian, incidentally, pushing Italian to receive an E so I don't understand how did Russian get placed in D? When there are nine letters in between R&H thus violating the rule? That they couldn't be placed in the same grading section? I would appreciate A comprehensive, elucidation, on this question I did watch the video that explains but was not elaborative in regards to covering every possibility Wrong v. Right

Hi, we have the following scenario in this question. We know that there are five possible grades, and we know the order of five of our six, G > P > E > H > I A: G B: P C: E D: H, R E: I There is no reason that you can't get the same grade in history and Russian.
