How to Choose the Right RBVP Project (Read Carefully)

This is the most essential part of your preparation.

Many students make a mistake here. They choose a project because it looks impressive. Later, they struggle to explain it. That creates stress and low confidence.

Instead, ask yourself these questions honestly:

1. Do I understand this idea fully?
2. Can I explain it without memorizing lines?
3. Can I make this using simple materials?
4. Does it connect to the RBVP theme?

If the answer to all four is yes, you are on the right path.

Here’s the truth.

A simple project explained clearly will always be more substantial than a complex project explained poorly.

Choose something you can own, not something you fear.
