Hii

Yes ofcourse you can. You need to work hard and work in a proper direction. Hardwork, dedication and honesty is the Key to cracking IIT without coaching.
Make a proper schedule and strictly follow it. Decide what are your strong areas and weaker once. Work on improving the weak sections and strengthening more your stronger parts.
Make schedule by putting physics for morning time, then take break, then in the afternoon focus on maths, and in evening work on chemistry.
Get proper study material and clear your basics with NCERT itself.
Practice alot with previous year papers as well as sample papers and be very very honest in solving these papers. Also keep a timer on while soling paper so that you know your speed and can improve your performance as well as speed.

Focus on tricks to solve the answers rather than wasting time on lengthy calculations.
Do not stress out. and do not study till late night. Take proper sleep so that your body and mind are relaxed.
Clear your doubts side by side and do not pile them up.
Keep revising and keep practicing.
