My son is a K1 student in KV now. Actually he is very happy and he likes his school very much. When you ask him: From Monday to Friday, which day you like the most? His answer is Monday, as he can go to school again.
About the homework, as he is still in K1, not so many at all. Only 1 page of writing per day and every kid and finish within 15 minutes. But I think it will be harder from K2 onwards.
