To find the score on the remaining test, first calculate the total points for all seven tests by multiplying the average score (88) by the number of tests (7), which equals 616. Then, add the known scores (91 + 91 + 92 + 82 + 91 + 70 = 517) and subtract this sum from the total points (616 - 517 = 99). The score on the remaining test is 99.
