This line of reasoning doesn't hold. You are comparing apples and oranges. A classroom examination can't be compared to murder, rape, sex slavery, slavery, etc. There is too much suffering in this world, what is Allah waiting for? If he is able to stop all the suffering, but he is not going to do it because he is "testing" us, then he is a sadistic, heartless, evil being.
Just shut ur creeping mouth if you have some confussions u can ask a good way wht is this way to ask So just keep ur mouth shutted we dont need ur questions we all know what is the real truth if u dont wanna believe the wait for the day of judgement u will get to know everything when u will burn in fire then u will see that the religion u follow leads to satan and u will say to allah that plz resend me i will live my second live as a true shia muslim
Oh mad all are the creations of allah wether he is evil or not allah is testing out his believers by the disbelievers if Allah just had to destroy the falsehood then why He created us were angels were not enough and if he created us then why he created the false hood he could have just created those who never omitted sins
