Re-took some Mathematic classes, to refreshen past memories !

Myself cheering-up after receiving a B+ in my 'Intermediate Algebra' class and an A in 'Trigonometry' at Miami Dade College (2010). I dropped
out of 'Calculus & Analytic Geometry (1)' (2011), after mid-term. I have passed this same Calculus class, twice before with a B (1980) and C+ (1985) respectively, at Springfield College in Illinois and the University of Illinois, at Springfield. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
