I totally empathise! I have had so much marking to do this term. Make sure you treat yourself to something relaxing and rewarding when you finish. Blessings.
My brother is an English high school teacher, so I can understand about you needing to concentrate on one spinning plate at a time. (You know those spinning plates on a stick, that can crash if you're not concentrating? ;) So take your time and I'd love to hear some stories about your teaching.
Thanks so much for understanding ladies.
