It will pull your average down. How much depends on how many 
tests you have already taken.  The more tests you've taken
the less the 78 will pull your average down.

  If you have |   a 78 on the 
an 85 average |   next test
on this many  |   will pull 
   tests      | your average
  already     | down to this
-----------------------------
     1        |     81.5   
     2        |     82.7
     3        |     83.3
     4        |     83.6 
     5        |     83.8
     6        |     84
