You may be on RC meanwhile the person next to you is working on LG and you can hear them tapping on their pencil. Make sure you take PTs in not too quiet areas. Sometimes in a coffee shop/park. To get a feel for it.
@emli1000 ... I hope the pencil markings didn't spoil it for you... sorry for not rubbing them out again :/ flaws were practically the only thing I did there :/
