This course is dedicated to Error Analysis and I have explained it from the very basic level to CSIR NET exam level. If you have problem with English explanation, hindi version of this course is also available, you can watch it here, https://unacademy.app.link/LAY1FbOkLQ
If you are preparing for CSIR NET in Physical Sciences, GATE Physics, IIT JAM Physics, SET/SLET, JEE etc.  like entrances then this course will be very useful and if u are a 12th standard student or Bachelor of Science or Engineering then this course will help you in practical examination because you have to calculate errors in your observation.
If you liked this course and found useful to you, please give a 5 start to my course and follow me on Unacademy.
