    Sir don't pay attention to the toxic people. You are simply genius. I was too weak in math. But as soon as I start watching your video, I am quite satisfy with my improvement. I qualify MTS 2021 with good score. Hope I will get a job. And my cgl 2022 was also good. Perhaps. I will qualify for main. Thank u sir.
