What is Heaven supposed to be like??

Can anyone help? I am a teen. My Grandmother of whom I was very close to died about 4 years ago. Only the thing is I still haven't really come to terms with it.The thing is when she died I I ended up due to circumstances an awful amout of high school. Therefore I missed pretty much all of my religious education and therefore I don't really understand where she's gone.
I have a question I was wondering whether anyone out there could possibly help me with. This is: what does The Bible/Christianity say that Heaven is like? What does it look like? (are there any descriptions) and what happens up there??
Also I hope this doesn't sound like a stupid question (only I just wondered because I missed such a lot of school) but do they give a good all-round general education in Religion in High schools??
What sort of things about religion do they teach you in England?
CAN ANYONE POSSIBLY HELP?????

hevan..

I go to school in wales which is in the uk by england and they teach religous education very well.
in the bible there are no descriptions of heavan it is judt simply were your spirit goes to be closer to god all the rubbish about it being in the sky is simply symbolic.
dont worry your grandmother is in a better place.

Heaven

Heaven is simply being with God whilst Hell is being without God, pretty much... hope this helps!

If you want to get extra information and description of Heaven, you can get it from Holy Quran. Peace be upon you...
