3 years before you plan to give exams start coaching. Choose your optional subject B4 hand so that you don't have to mug up just before the exam. If you are going to give exam next year, then you should start right now. Join coaching but if you can study by yourself, go to market and but books and give time to every subjects.

Depends on where you live. But, Delhi is the best place for UPSC coaching with hostel facilities too.

Hi Nawaz!
These are the top coaching centres in Mumbai for UPSC preparation:
1. The Prayas India, Andheri West
2. Success Forum, Borivali West
3. AA Shah's IAS Institute, Fort
4. Dronacharya IAS Academy, Navi Mumbai
5. Royale IAS Academy, Mira Road.

Hi dear,
That's a brilliant option that you have chosen, as an Honors degree will provide you weightage. Preparation for UPSC should be started once the 2nd year exams are over.
One year regular classes and thereafter revision for 3 months would be enough, if proper timetables are followed. Write back for further queries. Thanks and all the best.

See, there are various government exams that you can prepare for now you have to decide for which exam you want to appear.

Yes, you can. But you will have to manage both and study double time. You can join a coaching and prepare there at evening.
