To calculate the number of correct answers you got on a test, you can use the formula: (score / total possible score) x total number of questions. In this case, you got a score of 78 on a 65-question test. So, (78 / 100) x 65 = 50.7. Therefore, you got approximately 51 questions correct on the test.

In order to score 78% correct on a test with 150 questions, assuming that every one of the 150 answers is given equal weight, you must answer exactly 33 questions incorrectly. No more, no less.
Assuming each question is worth 1 mark, 78% of 32 = 78/100 × 32 = 24.96 As it is unlikely that you will get 0.96 of a question/mark, you will need to get 25 questions right to guarantee getting 78% - you will actually get 78⅛ % which would be rounded to 78% to the nearest whole percentage.
