The Varnas ordered from top (highest status) to bottom (lower status):
Brahmins (priests, teachers and scholars)
Kshatriyas (warriors, administrators and rulers)
Vaishyas (merchants and farmers)
Shudras (laborers)
Dalits (<em>avarna</em>)
As you can see, the Varnas are fundamentally 4. However there are certain tribes that don't belong to any Varna, such as the Dalits which are classified as <em>avarna</em>.
Hope this clears things up!
Direct democracy would be extremely costly because people would have to vote on every single thing and this would cost time and money to ensure everyone has voted. It couldn't be resolved in early times, but maybe with the age of technology, you could surpass that by having everyone vote online or something similar.
Yes they should. If high schoolers do not take a test colleges will not know who to accept. They should also to refresh their mind and see what areas they are good at. Now that they know what they are good at they can decide a college. That is why people should do have a test.
