On a test, students receive 3 points for each correct answer and are penalized by losing one point for each incorrect answer. There are 6 questions on the test and each question has 4 answer options, A, B, C, and D. It is known that 5 of the questions have option B as the correct answer and one question has option C as the correct answer. If a student marks B for the first 3 questions and C for the last 3 questions, what is the minimum possible score that student can receive?

A. -2

B. -1

C. 0

D. 1

E. 2

Kudos for a correct solution.

For the minimum possible score, let us take the worst case scenario

Suppose, he gets all of the last 3 qs wrong whose correct answer options are B and one of the first 3 qs wrong whose correct option is C

In that case, he will get only 2 out of the first 3 qs right.

Therefore, minimum possible score=(3*2)-(4*1)=2

Answer E
