Hello!
Does it make sense if i say like,

During the vacation, depending on how much time you spend on studying, or how well you have prepared for your study for the following semester, you will have a successful vacation.

also, what do you say making a plan for study?

Once you have made a plan for your study, you have to carry out your plan.(can i say like this?)

Looking forward to seeing your answers. Thanks a lot!!!!!!!!!!!
