Course end date for Child Benefit when continuing education

[JMELC]

Hi, feel very silly but I can't find the answer after some online searching.

I've made a claim for child benefit and need to give my 16 DS course end date.

He's expected to be in education for 2 years but the course is split into level 1 and level 2 for years 1 and 2 respectively.

Do I give the end date for level 1 and then notify them of going on to level 2 towards the end or do I just give the end date of the level 2 course?

I had to get a letter from the college as evidence, and used that date. Often end 3rd week June.

Because the course will start delivering the L2 content in year one, it clearly seems designed to be a 2 year course. I'd therefore put the 2 year end date. A college course can include multiple qualifications.
