The courses GRE2405 and GRE4408 have joint teaching in the spring semester 2023. Both courses are marked in their course descriptions as courses with Norwegian as the language of instruction, but with English as the language of instruction upon request. There has now been such a request to have English as the language of instruction, and therefore the language of instruction for the two subjects GRE2405 and GRE4408 in the spring semester 2023 will now be English.
