Driving License in BAHRAIN Inquiry!

Hello all,
i have a question as well as an inquiry, my test date will be later in this month, my question is that in the big roundabout inside driving school, how do i know which right to take when the moroor says to take right? should i take the first right or the second right?

my inquiry is do they allow minor mistakes to happen?, im extremely confident about my driving, like i have a very strong control of the car, but sometimes i mess up signals. also my instructor she didnt take me to the second roundabout, where one has to use the handbrakes!

Please anyone who has passed recently help me out?
thanks and regards

Always the first right if police said that if he doesn't say anything then the second because we always have to go straight and if police didn't ask anything then straight and if he say right then the first right

i made few mistakes but they gave me, n zaara is right
