"Student life is not the proper time to do things. It is the time to ‘prepare’ for things to be done in future." How does it sound??​

While I do get what you're trying to say, try rewording your sentences. For example, instead of saying "Student life is not the proper time to do things," you can use this: Being a student means that you can not focus on your interests and study for school assignments at the same time. You are, eventually, going to have to focus on one thing, either your interests, or school. As school keeps students busy with loads of assignments, tests, and exams that students can't find a proper time to do the things they want to do. (see how I used your sentences here?)

Try doing the same for your next sentence, and come back here!

the answer is option 1
