GTA SA: Driving School: How to pass "Alley Oop" mission with awesome tricks

Details

Description

This is my gameplay for Alley Oop mission in Driving School. I can make 100% (Gold) for it if I want. But when I'm recording,my gameplay is reducing its lagness,so my greatness is losing only when recording.
So,here's the tips and tricks:
1. First, go to the side where you're pro in rolling sideways(in car,not on foot). Example,me. I'm pro in the left side,so I went to left side while accelerating the car.
2. When you're near the ramp, only step the two wheels in the right side. If you're about to roll in left side, step the two wheels in right on the side-edge of the ramp. If you're about to roll in right side, step the two wheels in left of the side-edge of the ramp.
3. When the two wheels are in the side-edge of the ramp,do this step:
A. For left side:
*Press and hold the "left arrow key". When you're in air, then press the "down arrow key",don't release the left arrow key.
*While pressing "down" and "left" arrow key, then press and hold "D".
*When you're landed, release all what you're pressing then press S to avoid the car getting upset.
(So,the whole code for the left side is = Left Arrow Key + Down Arrow Key + D,then release all the key, then press and hold "S")

B. For right side:
*Press and hold the "right arrow key". When in air,then press the "down arrow key",don't release the right arrow key. While pressing "down" and "right" arrow key,then press and hold "A".
*When you're landed back on the land, release all what you're pressing then press and hold "S" to avoid the car being upset.
(As similar as for left side,but the "down arrow key" and "S" were not changed. The code is = Right Arrow Key + Down Arrow Key + A,then release all the key, then press and hold "S")

*Didn't get what the left side or right side is? Let me explain.
The left side is what I'm talking about that where I would like to spin to. I want to spin left,so I'll go to left side. I want to spin right,so I'll go to right side. Hope you got it now!
Just follow the instructions then you'll get great achievement.


Notes:
* Neither cheats nor mods were used. And yeah,I'm using too many mods,but it doesn't affect the gameplay. I don't use handlings nor skins, I only use scripts. Including Cheat Menu, Parkour, Walkstyles, 4ni and DYOM. So, if you think I used handlings, then okay,say it here! I don't care,but I didn't use handlings.

* For those who are not pro in racing,practice racing first. Because being skilled-guy in racing(not in real life,but in GTA) can affect all the tricks like this mission in Driving School!

* For those who are pro in racing for now, you may do this and I'm sure you'll receive great award. Unlike for not pro in racing, because they'll say that this gameplay won't work,because they're not pro yet!

* Take note that you won't do this gameplay perfectly when you see this gameplay for the first time. It takes much time. So you need to practice carefully. And do as I did and what I typed in Tips and Tricks.
