At my university, there was an intro to programming course which used Scheme & was inspired by SICP. I took the course with previous programming experience (Java, Python), and found the course straightforward. I also knew students who took the course having programmed in C++, and who struggled with the course.

I'm not sure "do SICP exercises in scheme having learned Python/C++" is really about transferring programming fundamentals. The SICP exercises seemed really geared towards a small lisp.
