Conscient vs. au courant
Both conscient and au courant translate to aware or conscious in English, but they are used in entirely different contexts. The difference lies in the depth of knowledge: conscient refers to a deep internal understanding or realization of consequences, while au courant simply means being informed about a fact, piece of news, or event.
Conscient
The word conscient means being deeply aware of a situation, realizing its gravity, understanding its consequences, or being medically conscious. It implies a mental, moral, or psychological realization rather than just possessing factual information.
Je suis conscient des risques que je prends.
(I am aware of the risks I am taking.)

(He is finally aware of his past mistakes.)

(The patient is still conscious after the shock.)

(We must all be aware of our impact on the planet.)
Elle agit sans être consciente du danger qui l'entoure.
(She acts without being aware of the danger surrounding her.)
Au courant
The expression au courant means being informed, up-to-date, or possessing factual knowledge about a specific event or news. It is used when someone has been told about something or is simply keeping track of everyday occurrences.
Je ne suis pas au courant de ce changement de programme.
(I am not aware of this change of schedule.)

(Please keep me updated on your arrival time.)

Summary
To choose the correct word, ask yourself about the nature of the awareness. Use conscient when you want to express a deep, moral, or consequential realization, or when referring to someone who is awake and medically conscious. Use au courant when you simply want to state that someone has been informed about a fact, a piece of news, or a specific event.
