Question

Are the "worked examples" of the same difficulty level as part2 of the problems sets on the other versions of this course?

Answer 1

You should be able to learn calculus with the SC version. If you like, you can tackle the problem sets in the 18.01 course, but I don't think answers are provided.

Answer 2

altogether, there are three versions of 18.01, one of them has problems sets with a part1 and part2( along with the solutions) but is the syllabus covered the same as those in the video lecture? (its a different professor)

Answer 4

Yes, I believe they all cover the same basic syllabus. The non-SC versions are the courses an MIT freshman takes. You can use them, but there are some short-comings:
1) no Teacher Assistant sessions, where the material is reviewed
2) no cooperation with other students (often the Part 2 problems are tackled as a "group")
3) Answers not provided for the problems.
