Both conception and assent are subdivided into badihi (immediate or self-evident) and nazari (requiring reflection or inference).
Badihi knowledge is obtained without organizing a further process of reasoning at that point.
Nazari knowledge requires thought, analysis, or reasoning from what is already known.
This division concerns how knowledge is obtained, whereas the conception/assent division concerns the presence of judgment.
Thus a conception can be immediate or inferential, and so can an assent.
