Do We Graduate?

There is so much information here, I'm sure the answer is right in front of me but:

  It seems to me the purpose of the soul/consciousness is to learn and love or vice versa.  I understand we start at a a particular vibration and as we progess through life and with the right intention we increase our vibration and knowledge. So, does that process continue forever? Are our souls really eternal or is there a graduation point? If there is a "double Black belt"? If so, then what? I mean do we get absorbed into Source or something or do we recycle to maybe another life form or just exist in some kind of bliss?
