Be more conscious about your rpm and speed at each stage of the
gear. You must have this mindset that you are the one controlling
the gear and the type of speed you want. As many had said, find the
biting point of the clutch. When release clutch, dare to press on
accelerator, don't "let go oil", otherwise you will get that "jerk"
coming from the "engine brake" (I think).
Then slowly you will find yourself not worry about jerkiness. A bit
more work but more rewarding than driving an auto.
But then it takes really more experience to achieve really smooth
driving. I'm not there yet

Maybe ask [email protected], I bet he's a solid driver !
