I went to a Zoom party with some guys from Lithuania, the conversation suddenly turned to studies and someone mentioned Killer Papers. They said, "it seems okay, but read the reviews". I went to https://nocramming.com/killerpapers-review - and for good reason! It's a case-by-case analysis: where the service is good, and where it can let you down. Now I know exactly what to expect and when to contact them.
