Stepdaughter learning how to drive a 4 speed
When I had a stick on a hill. I would heal toe the brake and gas pedal.
Then ease on the clutch till I felt the engine start to pull, then add some gas and when the van could start to hold its own let off the brake.
Also a cheat is to use the parking brake and then clutch and gas till it was pulling on the brake and release the parking brake.
Another thing I would do on a hill, is if there were cars behind me I would almost stop well behind the car in front of me, then after the car behind stopped I would creep forward to have a few extra feet, and come to a full stop.
