Nobody knows, if God is real and you get sent to hell by him, who do you appeal to? Your best bet is to get family, friends, holy people or prophets to beg him on your behalf. He'll for eternity for failure to pass the tests on earth will be bad. But I think there will be some kind of meritocracy to getting into heaven. If there was one. What if hell and heaven are on here on earth, imagine bringing into a rich family in Finland, all things being equal then imagine being born into a trailer park in America, that might be hell all things be equal. Who know what happens.
I will advise you make atonement for your sins and aks for family to pray for you after you have long gone, those are your best bet other than you can't do much. I hope we all see each other in heaven. Especially those that earth has treated badly.
