Thanks for the advice, i feel i should probably make a clarification though in case anyone's gotten the wrong opinion of the Chu Shong Tin academy they don't follow any belt system at all from what i've read. when i mentioned grades/levels, what i meant was that each one has its set curriculum of information for the student to absorb and become proficient with before moving onward, i.e.
Grade 1
Basic theory and logic of Wing Chun,
Siu Nim Tau form,
Wing Chun stance and its importance,
Pivoting,
Development of punching and kicking,
Counter-movements to basic arm and leg attacks,
Counter-movements to basic rear and side attacks.
Grade 2
Single Chi Sau (sticking hands) and basic applications,
Development of the Siu Nim Tau form,
Further development of the Wing Chun stance,
Cultivation of 'forward force',
Four corner deflection techniques,
Development of punching and kicking power,
Counter-movements to advanced arm and leg attacks,
Combination and extension of Grade 1 movements, with an emphasis on fluidity of movement, speed and reflex,
Limited sparring.
etc. etc. up to lvl 6 when they teach you either the vulcan nerve grip or the touch of death.

kidding the closest it gets to that stuff is something called vortex effect, still sounds awesome though.
And yeah the WSL Ving Tsun, i took notice of because Wong Shun Leung is the guy that used to either train Bruce Lee or train
With Bruce Lee, i cant recall precisely... possibly both with how martial arts schools work; the older students helping to teach the younger, they mention WSL a few times in documentaries about bruce lol i vaguely recall him having something to do with game of death.... either choreographing a fight or sparring backstage with extras some-such non-sense lol but don't go quoting me cause i'm probably wrong and then you'll sound silly for being wrong as well
