The recommendation for Calculus 2 is:
https://www.coursera.org/learn/advanced-calculus

However, this course skips a good deal of material generally taught in Calculus 2, including Parametric curves and polar coordinates. Students will need both if they continue on to Multivariable Calculus in Advanced Math (which itself is a pre-req for Probability).

I would recommend replacing the current Calc 2 course with:
MITx: 18.01.3x Calculus 1C: Coordinate systems and infinite series
