Amazing science teacher! Looked like the hardest and meanest teacher with his lab coat on but turned out to be one of the most interesting and funny teachers.
Mr. Johnston made chemistry so interesting that when you left his classroom you never forgot the things he taught you.My brother told me he used Mr. Johnston's notes to study for his university exams
Mr.Brian Johnston: Probably the BEST TEACHER i ever had, i have ever met. EXTREMELY ORGANIZED, VERY CLEAR, TEACHES AMAZINGLY, EXCELLENT in every way
