Natives correct me if I'm wrong, but this sounds a tiny bit strange:
כרגע is like "right now" "at this moment". I would have said עכשיו הבנתי.

 

You're probably right, my Hebrew is not so good.

 

You're right. We use it for something that is happening right now or something that has just happened.

 

maybe, but i think its correct, though i wouldve said הרגע and not כרגע.

 

I assume you would have said הרגע הבנתי (something that has just happened), and not הרגע/כרגע אני מבין.

 

Well yes, but as a student in a really difficult field (CS) i would totally accept כרגע אני מבין

 

כרגע אני מבין, אבל עוד כמה שניות לא בטוח...
