Simply put, I don’t quite like the idea of reviewing because I feel it takes time and I don’t like repetition or monotony that much (In fact, one of my reasons for getting into memory techniques was thinking that I could totally escape reviewing, you can imagine my surprise 
). I also procrastinate quite a lot. With exams coming up very soon, I am thinking I may be benefitting by reading later so that I won’t have to review as much, is this a reasonable line of thought? I am not quite interested in retaining the information long-term for now (they are mostly courses that will not be helpful to my future career).
Also, while on the subject of reviews, when learning a large volume of information, do you review only the memories in your head or you go back to the source material?( I ask this because the knowledge seems to reduce over time, leaving only the images you formed. For example, if I were to encode that “the transfer of materials from gametophyte to sporophyte in bryophytes is apoplastic (through cell wall) because there is no plasmodesmata” with four images representing : sporophyte, gametophyte, apoplastic, no plasmodesmata (I put the apple (apoplastic) on the wall to remind about cell wall), without going back to the source material, the information may continously reduce till I am stuck with just the images and not much filler.
