The water from my bathroom tap comes out at an angle (as though I had my finger over the stream). The direction of the water changes as I turn the tap. It also makes squealing noises and sometimes sputters, making loud knocking noises when it does.

It behaves better if I run the shower at the same time. If I tighten it shut really hard, sometimes it will return to normal for a bit. I mostly stopped doing that though cos the seal broke and had to be replaced.

What's wrong with it and how hard is it to fix? I have zero plumbing experience.

Coming out at an angle suggests that there might be deposits stuck inside the aerator. Sometimes this is as easy as unscrewing the aerator and removing the rocks and sediment found inside.

The sputtering and loud knocking noises suggest there's a bubble somewhere in the plumbing in the walls that is causing a water hammer. One possible way to clear this bubble is to fully open all plumbing fixtures at max, which will create enough water flow to push a bubble out. It's kinda like burping the pipes. You should do this with all aerators removed.
