This is a very unfortunate event. Now its not sure that the weightage for the session of 2022 will be waived or not. But as per the internet, there are possibilities of the same. So if you have not enrolled yourself in anything else then you should keep on preparing for the JEE 2022 and if you get that the weightage isn't waived then also you can appear for other entrances to get a career ahead. JEE is not the only way to get success in life, the success is you and not the degree/college you are in. So don't get demotivated and keep on working. I wish your hardwork must get its proper evaluation.
