Open Quote as a graduate and therefore an alumni of ps 99 (Pre isaac asimov) although i read his work extensively in those years. at my present age of 67 i can truthfully reflect on the quality education that i began my life and career with. in particular,my french teacher in the sixth,seventh,and eighth, marie a. howes, was by far the best teacher i ever had in my life. she is long gone but most certainly deserves the credit due a caring and beyond excellent teacher. ken lee 908-303-7661 thank you and continued good work Close Quote
