Abstract
Previous work has mostly investigated the top errors made by novice Java and Python learners to explore enhancing error messages, manifestation of misconceptions, or inform instructor decisions.

We generalized errors into categories to create a language-independent set of the most frequent and most difficult-to-resolve errors.
