yes you are correct ayesha_Ras, driving test now is such a head ache here, tho i just took it on first attemp but my friend got a hard time on it,

signal test will be like this - 20 question computerize and you should have 19 correct answer, if you got below 19 you're failed, after passing the computer test they will bring you, its either they will use actual cars or pictures of the bonnet(engine and other internal parts of the car) as per my exam they brought me outside and use actual cars, the policemen will ask you what are the parts he is pointing, take note (the randomly use manual or automatic cars which they have different position of parts so be careful on the pictures)

i passed the exam (2nd attempt on signal test & 1st attempt on parking test & 1st attempt on road test)

Best of luck, pray before going to the driving school!
