I know that when approaching from the North you pass to stbd. But what about when approaching from the south? Is it the same, need the answer for YM homework, notes at home.

I always had trouble with this one, but it's much better you figure this out than anyone gives you the answer. The only point in doing the course is so you have skills to take into the real world.

I think it rather depends on what sort of cardinal mark it is - and what it is marking.
The real answer is that a cardinal doesn't tell you much unless you can identify it on a chart.

A Cardinal Mark beit North, South East or West Marks that side of the danger.
So if you approach a North Mark 'from' the South without passing a South mark your bascial in trouble your in or on the danger area.
Draw a circle 'the danger area' put in the N, S, E and W points and you will see what I mean.

It is a question in the homework on lights. The question is 'You are heading into harbour at night, when you see this light do you alter course to port or starboard?'
I presume that there will be N,E&W marks as well around a point of danger.

"I know that when approaching from the North you pass to stbd. " Try that with an East Cardinal and see what happens.Whoops! Forget all that and just remember that the danger lies to the centre with the cardinal on the outside.EG North cardinal stay to the north of it, West cardinal stay to the west of it. South cardinal stay to the south of it, east cardinal stay to the east of it. Hope this helps.

No not if the danger is for example a sandbar or shoal of a headland. Then you may have only one mark. The mark indicating the side of the dander its marking.
So if your cruising along the South coast for example and you come to a headland with a shoal extending out from it, say due south. Then you would come across a South Cardinal Mark - marking the Southern end of the shoal.
Entrance to a harbour, first check your chart. The harbour wall or walls will be marked with red or green lights. If its a harbour like Dover it could have 'In and Out' lights as well.
If a boat is coming out of the harbour towards you check its red or green you see than the rule is red passes red.

Re: South cardinal mark
Q (6) = quick 6 flashes, L Fl.15s = one long lasts 15seconds == South Cardinal Mark

This is a South Cardinal, which means it is South of the danger.
If traveling from the South to the North and reached this mark - continuing North would put you in danger.
