which one is grammatically correct:

or Best of luck with your studies.

Kindly clarify.

Best of luck with your studies

Thanks for the answer.

So if " best of luck with your studies" is right than is " Best of luck with your exams " also right? or should it be " best of luck for your exams" ?

Kindly explain the grammatical logic behind it if possible.
