After being a tutor of statics for good amount of time, i noticed the reason behind the failure at this subject is lack of understanding at some of these following simple subjects
So created an webapp which provides some questions and lets you upload your hand-written solution then evaluates and gives recommendations referring to these 7 subjects. For these 7 subjects there are also interactive applications to get better at them.
Feel free to visit StaticsCoach.xyz to test it.
Once upon a time, i was a tutor of it.
