Help me with this logic problem?

This is for extra credit for my Algebra 2 class. I’ve been trying all night and haven’t been able to get this. Six high school seniors were scheduled to take the same six classes in a different order. Each teacher (including Mr. Conley) instructs six sessions of his/her class, three in AM and three in PM. The floor plan is such that the second floor has the same layout as the first, with room 205 directly above 105. Can you determine each room’s teacher and class, as well as each student’s full name/schedule of six classes? (floor plan looks like this) 201 203 205 101 103 105

1. Kathy has math the period before Lori, and Kathy has computer science the period before Matt.
2. Don has English, Ms. Ritter’s Class, and the class that meets in room 203, in some order, during the afternoon. The student with the last name of Auger has the same three classes in some order during the morning.
3. Keller (this is a last name) has computer science later in the day than Spanish.
4. Ms. Ritter has Lori in class earlier in the day than she has either Matt or the Green (last name) girl.
5. The student surnamed Ellis has Spanish in room 201 sometime during the morning at the same time that Matt has English and Don is in Mr. Schott’s class.
6. One student’s class schedule is, in order, Ms. West’s Class, the class in room 103, history, math, Mr. Thal’s class, and English.
7. Ms. Thomas has the Dixon girl in her class the period before she has Don, but later in the day than she has both Judy and the Moore (last name) student.
8. The chemistry class meets in the room directly below the math class, and right next to the English classroom.
9. Gil has History in the morning, just after his class in room 105 and just before he has math. His English class meets in the afternoon, just after Keller’s.
10. Judy has class in room 103 during sixth period, and the class in room 201 sometime during the morning.

The six students are Judy, Kathy, Lori, Gil, Don, and Matt. The six last names are Keller, Ellis, Green, Auger, Dixon, and Moore. The six teachers are Ritter, Conley, Thomas, Thal, West, and Schott. The six classes are Spanish, Math, History, English, Chemistry, and Computer Science.
