Hello,

Preparing the timetable is something you have to on your own, the reason being you know yourself the best, not everyone can follow the same routine, what works for one individual might not be the same case for other, also you're in college hence your academic studies too are important,  UPSC covers such an extensive syllabus hence it helps if you can make a timetable on daily, weekly, and monthly basis, by doing this you won't lag behind, another important thing which  I can tell you is start in a gradual manner, such as go through the syllabus of UPSC, take a print out and learn it by heart, as this will enable will you to focus on what to read and what to skip, make a habit of reading newspaper everyday with emphasize on editorials national and international news, economy, polity, science and technology etc, if you find any topic important you can also makes notes whether it's digital or handwritten as per preference. when it comes to study materials NCERT books are the foundation, hence build the base strong, and then move towards the standard books such as

For Prelims, you can refer the following books:

For GS IV - For Ethics refer a book named Lexicon by Niraj Kumar, also you can go through study material of IGNOU.

Always keep your resources minimal, and revision is the key here, read one book many a time than many books one time.

Go through previous year papers for practice as well as understanding the paper pattern, type of questions etc, you can get it at the official website of UPSC, also practice answer writing in advance as writing mains is huge task, you should consider going through topper's answer sheets in order to get an idea about how to present your answer, try to offer a holistic answer in terms of political, social, geographical, economical sense. when you will be about to appear for the exam, apply mock tests on regular basis to analyze your preparation.

I'll again emphasize it's good you want to start early for UPSC but don't neglect your studies, as UPSC is conducted over a period of two years, one year for preparation of exam and another one for appearing in the exam, hence sustaining the inner drive, motivation is of immense importance, it requires single-minded focus, dedication and perseverance to succeed this exam, for starters go through the syllabus regularly, read newspaper such as The Hindu/The Indian Express. and read NCERTs to build the base strong. and later move towards covering the other areas of preparation.
