     "....The only problem was this: because the timetables often took
      seven or eight weeks, and sometimes more, to complete, by the time
      Rimmer had finished then the exam was almost on him. He'd have to
      cram three months of astronavigation revision into a single week.
      Gripped by an almost deranging panic, he'd then decide to sacrifice
      the first two days of that final week to the making of another
      timetable. This time for someone who had to pack three month's of
      revision into five days.
          Because five days now had to accommidate three month's work,
      the first thing that had to go was sleep. To prepare for an
      unrelenting twenty-four hours a day sleep-free schedule, Rimmer
      would spend the whole of the first remaining day in bed-to be extra
      ultra fresh, so he would be able to squeeze three whole months of
      revision into four short days.
          Within an hour of getting up the next morninghe would feel
      inexplicably exhausted and start early on his supply of Go-Double-
      Plus caffeine tablets. By lunchtime, he'd overdose, and have to make
      the journey down to the ship's medical unit for a sedative to help him
      calm down. The sedative usually sent him off to sleep, and he'd wake up
      up the following morning with only three days left, and an anxiety that
      was so crippling he could scarcely move. A month of revision to be
      crammed into each day.
          At this point he would start smoking. A lifetime non-smoker,  he'd
      become a forty-a-day man, He'd spend the whole day pacing up and down
      his room, smoking three or four cigarettes at a time, stopping
      occasionally to stare at the titles at his bookacase, not knowing which
      one to read first, and popping twice the recommended dosage of dog-
      worming tablets, which he erroneously belived to contain amphetamine.
          Realizing he was getting nowhere, he'd try to get rid of his soul-
      bending tension by treating himself to an evening in on of Red Dwarf's
      quieter bars. There he would sit, in the plastic oak-beamed 'Happy
      Astro' pub, nursing a small beer, grimly trying to be light-hearted and
      totally relaxed. Two small beers and three hours of stomach-knotting
      hours later, he would go back to his bunk and spend half the night
      awake, praying to a God he didn't belive in for a small miracle that
      couldn't happen.
          Two days to go, and ravaged by the combination of anxiety, nicotine,
      caffeine tablets, alcohol he wasn't used to, dog-worming pills, and
      overall exhaustion, he would sleep in till mid-afternoon.
          After a long scream, he would rationalize that the day was a total
      write-off, and the rest of the day would be spent shopping for the three
      best alarm clocks money could buy. This would often take five or six
      hours and he would arrive back in his quarters exhusted, but knowing that
      he was fully prepared for the final day's revision before his exam.
          Waking at four-thirty in the morning, after exercizing, showering,
      and breakfasting, he would sit down to prepare a final, final revision
      timetable, which would condense three month's revision into twelve
      short hours. This done, he would give up and go back to bed. Mybe he
      didn't know a thing about astronavigation, but at least he'd be fresh for
      the exam the next day.
          Which is why Rimmer failed exams.
          Which is why he'd recived nine 'F's for fail, and to 'X's for
      unclassified. The first 'X' he'd achieved when he'd actually managed
      to get a hold of some real amphetamines, gone into spasm and collapsed
      two minutes into the exam; and the second when anxiety got so much of
      him his subconcious forced him to deny his own existance, and he had
      written "I am a fish' five hundred times on every single answer sheet.
      He'd even gone out for extra paper. What was more shocking than anything
      was that he'd thought that he'd done quite well.
