Depending on context, I am very happy can be translated as:

Ich bin sehr glücklich

Ich bin sehr froh

It depends. Do you want to know when school ends like "When do you get home after school" or more like "How many years do German students go to school"?

At first you have to know that we have got a few different school types. Children go to the Grundschule when they are about six years old and they stay for about 4 to 6 years. This depends on the Bundesland (state) you´re living in. I for example went 4 years to Grundschule and then changed to the Gymnasium. I live in North-Rhine Westphalia and here it used to take 13 years (including Grundschule) to complete school but they are changing the system at the moment and they are reducing it to 12 years.

But there are also some other school types like the Realschule (10 years), Hauptschule (9 years i think) and the Gesamtschule (i think either 10 years and if you choose to do your Abitur - the highest degree you can get, you need it to go to university - 12 or 13 years, too). As you can see the education system in Germany is quite complicated and that´s why they are trying to change it.

But if you simply wanted to know when kinds get home after school, well that is that easy as well. When I was in fifth grade school started at 8 a.m. or sometimes at 8.45 a.m. It usually ended after 5 or 6 lessons at either 12.25, 13.15 or sometimes at about 2 p.m.

But it really was not like every day you´d come home at the same time. Sometimes you only had like 4 lessons or something. But that has changed, too, today the fifth graders stay in school up till 3 p.m. For me this is strange because when I was at their age I never had to stay longer than 2pm. Of course when you get older you have to stay longer, in the Oberstufe (11th grade to 13th grade) it is normal to stay that long at school. But it totally depends on your timetable. I´ve got friends who have got 10 lessons a day and on another day only 3. I was lucky because my lessons were very well balanced over the week.
School typically begins at seven am and ends at one pm. The start and end times vary based on the school.

Spaghetti is the most common and popular in Germany.

*Different provinces in Germany enjoy different foods. In the north "Gruehnkohl" is very popular. If you go to the southern region in Bavaria, they are not very familiar with Gruehnkohl. In Bavaria "Weisswurst" is very popular - it is a type of sausage.

Almost all Germans, no matter the region, love hamburgers and currywurst. Currywurst, which is a type of sausage (bratwurst,knackwurst, rindwurst) consists of the sausage being sliced into pieces, and then covered in a curry sauce which normally consists of ketchup or tomato paste blended with curry powder.

Germans also enjoy "Rotkohl" (Red Cabbage), "Erbsensuppe" (Split pea soup), "Linsensuppe" (lentil soup), and any meal consisting of meat and potatoes with gravy.

Schnitzel is also very popular. Schnitzel is sort of like a breaded pork chop. I most certainly can't leave out the "pommes" which are french fries.
It really depends on what region you visit, but overall the number 1 favorite food in Germany is Schweinebraten.
bratwurst is Germanys favourite food
