Will the UK be able to witness the tetrad in April 2014? I live in the UK and am aged 15. I have become extremely interested in astronomy, astrophysics, the lot. Basically I have never seen a tetrad and believe this will be my first time - at least understanding what it is. I'm hoping it will be possible and if so where will it be seen in the sky? As in North, South etc. Thanks!
It is great that you have an interest in astronomy.

Unfortunately, the UK will be on the wrong side of the Earth to see the lunar eclipse on April 15. If you you want to experiment with various places on earth that will see it, and what they will see, get a planetarium application like Stellarium or SkySafari or TheSkyX. 

A lunar eclipse is always easy to spot - it is where the full moon is. Also, because it is the result of the Earth getting in the way of the Sun shining on the Moon, it is always after the sun sets and after the full moon rises in the East. That is, if you're going to be in a place to see the whole sequence, not just a part of it. 

Just so you know, the tetrad is not one but a series of lunar eclipses over 2 years, this is just the first lunar eclipse in the series. The last tetrad was 2003-2004, so you were around, but probably not paying as much attention at that time :-)

Unfortunately, Cambridge UK will not see any of the first 3 eclipses in this tetrad. However the 28 Sept 2015 eclipse will be visible from that location.

Incidentally, one of the better places to see this lunar eclipse will be Easter Island (Rapa Nui) which will see the whole eclipse, and with the totality occuring high in the sky, near the meridian. Also, not much light pollution.
