edX vs Coursera for Data Science

edX if you're aiming at grad school or want academic rigor (MITx MicroMasters, HarvardX flagship courses). Coursera if you're aiming at hiring (IBM, Google, Meta Professional Certificates) or want a faster path to a recognizable resume credential. Both are excellent — the choice is about your end goal.

Yes, with conditions. The MITx Statistics & Data Science MicroMasters can be applied to MIT's on-campus DEDP MS program if you're admitted. Several other universities (Boston University, Curtin, RIT, Doane) accept specific edX MicroMasters as transfer credit. You still apply and must be admitted to the host program — the MicroMasters strengthens the application but doesn't guarantee admission.

Yes — most edX courses can be audited for free, including HarvardX CS50 and MIT 6.86x. Auditing gives videos, readings, and most exercises. The verified certificate ($50-$300) and MicroMasters credit require payment.

Coursera Plus is $59/month or $399/year for unlimited access to most specializations and Professional Certificates. edX charges per-course ($50-$300) for verified certificates and ~$1,500 for a full MicroMasters. For learners pursuing 3+ Coursera specializations in a year, Coursera Plus wins on total cost. For one specific MicroMasters, edX is more cost-controlled.
