In fact, the probability of winning prizes in math and physics competitions is similar. Depends on which one you are good at. In fact, there are a little more people taking part in the math contest than those taking part in the physics contest, but they are similar. So the chances of these two winning prizes are similar.

Compared with biology, fewer people take part in the biology competition. So biology is more likely to win prizes. But don't go if your biology is not good.

In fact, the key is to see which one you are good at and which one is easy to win the prize.

I wish the landlord academic progress.
