I'm a B.Sc student. I want to prepare for IITJam Chemistry without coaching .tell me about some apps & website through which i can prepare.

Actually you can get each and every detail about IIT JAM on careers 360 app and if you want to attend lectures than I prefer unacademy app as their are many choice you have . you can select your teacher and you can download slides or notes from that videos. For previous year question you can visit iit jam website their is all question paper available with answer key. But stay with careers360 as it gives good information and update about iit jam.
