can I crack IIT jee by doing self study and online classes my home condition is not well

Dear student,
You can definitely crack jee by self study and online classes. There are been many students in the past who cracked jee by self study alone. Just believe in yourself and work hard. Although you need to put more efforts in self study but if you want to achieve something great then you will have to work hard for it. Make a timetable and follow it strictly. And do not procrastinate your work.
