Harry Now i don’t know really what I should do.
Unfortunately, the contract has already been signed, so my concerns may be too late, but I still want to say something about it. The first point relates directly to this, you actually need a lot more time to work out the contract. You have to think about what your goals are and what means and rules you will use to achieve these goals. This contract sounds like a slave contract and goes far beyond improving grades in your studies or better behavior. On the other hand, you wrote that your parents were never particularly strict and then they should enforce this "slave contract"? That seems illusory to me.
Harry My parents I’m not the kind of that talk much
Unfortunately, this is a very bad precondition. The situation can always change and it needs to be discussed
further suggestions
end date: when you finish your studies and/or move out and/or get married the contract should end
you should be allowed to terminate, albeit with a waiting period in which you can change your decision again
