Is a bridge course before Calc AB necessary?

Thank you, for your response. After IA, Ib in 8th grade they take 2A,2B followed by 3A, , after which precalc-1( many skip this) concurrent with 3B.

After this Bridge to AB (many skip this too)

AP Calc ->AB AP Calc-> AB ->Pre-Calc 2 (not recommended for skipping)

Did have A or A+ in Math all thru’ middle school.

Thanks again for your help!
