Hi

Stop worrying and Change your preparation strategy!. Don't do the same thing again and again and expect different result that doesn't happen. Mathematics is conceptual never ever mug up ,try to solve as many previous question papers as possible. Its important to clear backlogs but that doesn't mean you are over I have seen an engineering failed student resuming studies again and pursuing his studies abroad and he's doing great so its not the end of the world. Don't let your determination waiver. Shut down all social medias and Concentrate more on the task. Let it be now or never. Don't keep any regret later. Try your best!

There is always a way if you have the will.

If I didn't get your query clear let me know.
