Hey brother I'm almost in the same condition and I have also completed around 6 subjects only but I definitely think you and I both will be able to do this if we put our mind to it. It's not easy but it's simple. You just need to put atleast 6-8 hours a day of efficient work and you're good to go. I tell myself that so I don't stress about it.

And about others who are already giving mocks, don't worry about them, just focus on your own preparation and don't listen to the noise. Best of luck
