Let's say I've finished 1st learning/studies stage out of 3 and being asked what is my motivation to proceed to stage 2 or 3. As a part of my answer I want to say that I wish to "*consolidate my knowledge*". (*knowledge consolidation*)

Question: What are the synonyms to this phrase? I've tried to find this phrase on Google but the results are scarce, thus I feel that there is a more natural/native variant.
