new Judge has an important point and you need to consider it especially with your intended route as a sheep farmer.
University and associated costs could cost you between £20k - £40K, and much of this would exist as a debt to be repaid.
If you take that value, and instead use it to fund yourself to get the practical skills and contacts needed to get your farm, it might work better for you.
So looking out for work experience type posts and looking directly for work in the sector might be better in the long term than going to agricultural college straight away.
