Well teachers usually consider your mid-term assessments in predicting your grades, so don't just rely on your AS assessments.
If I were your teachers I'd be inclined to predict you ABBB to be on the safe side as A2 gets harder which means it will be harder to get another A or another B and so forth.
A lot of teachers and schools nowadays aren't being careless with predicting results as most schools are all about exam factories and results. And if they over predict teachers' jobs can be on the line so I would defo say ABB.
But as I said, do well on your term-assessments and they might raise your predicted grades if you're showing a clear and fast improvement to learning.
