I am a undecided major freshman and wanted to transfer into Engineering major.
I have AP credit of Calculus BC (score 4)
Should I use this credit and take Calculus 2, 3 or
Just Calculus 1 to get easy A for GPA to transfer?
Do the college consider difficulty of courses or just GPA?

What college are you at, and what specific engineering major?

There is likely a web page that tells you what the requirements are to change major, and if it is selective by GPA or other criteria.

To determine whether you should take calculus 1, 2, or 3, try the old final exams for calculus 1 and 2. Based on how well you know the material, you can make a suitable placement decision.

If you cannot find your college’s old final exams, you can try these web quizzes:
