Yeah. The question was pretty simple. no algebraic processes were required.

 

[HIMYM forever!!]

I guess i attempted 96-97 questions. 3 or 4 are definitely wrong i know But there may be more of 'em wrong.

 

[HIMYM forever!!]

well m expecting to get 86-87 percent on test.....do i have a chance in pieas......there are 180 seats there

Well you can never be sure because there are very limited number of seats. But if you ask me, i think you dont have much to worry about. You got a pretty good chance.
