Before I answer your question please understand that every teacher at unacademy is amazing in his own have been a plus member of it from some time and with full assurity I can say that you will gain something extra from everyone.. But according to my experience I'll share the teachers whom I highly rmend POLITY Bare Acts course by Mudit Gupta ( Amazing course though lengthy but this exam deserves that hard work. Laxmikanth DD basu Bare acts have been covered in that course. USP is that he will make you write notes) Dr. Sidharth Arora sir ( Amazing teaching those who love to make notes go with him. But you need to know some basics of polity before starting his course. Freshers may find that he skipped many points from the topics but in reality they are the basics which he expects you know. He teaches from his experience and you will find amazing facts that are mentioned in his book) GEOGRAPHY & ENVIRONMENT Rizwan Sir ( He will teach you from basics to advance. You will find the books to be easy and of low level after watching his videos. He makes you write notes of each topic.. ) ECONOMY Mudit Gupta Sir ( He would make you write notes from basic to advance. I need not say much because you yourself will experience the change after thepletion of course.) Mrunal sir (The best teacher of Indiayou don't require anything for his class except full attention. He provides you with handouts and they are more than sufficient. I would advice you to make your notes with the help of above teachers before enrolling for mrunal sir's course otherwise you might feel burdened after some classes as a lot of things are discussed in just one class) ordered-list
