Common mistakes Nepali students make in olympiads

After going through pre-selection and a few selection rounds, here are the mistakes we saw repeatedly:

1. Rushing past the question

Olympiad questions are designed to trap hasty readers. Read twice: once for the setup (diagram, knowns/unknowns), once for what is actually asked for. Many people lose marks by giving the wrong quantity.

2. Solving for something else first

If the answer asks for "the magnitude of acceleration in the lab frame", don't stop at the relative frame value. The problem says "in the lab frame" for a reason.

3. Poor graph skills

At selection/camp level, graphs are almost guaranteed. The most common errors:

• Using too small a triangle to compute slope
• Connecting points instead of drawing a best-fit line
• Wrong linearisation (forgetting the intercept or units)

Fix: Practise two graphs per week by hand. Measure slope from two well-separated points on your line, not from the data points.

4. Ignoring uncertainty

Many students treat numbers as exact. Olympiads expect a sensible uncertainty treatment in lab rounds. Even in some theory rounds, a reasonable order-of-magnitude check shows physical intuition. Always write a quick sanity check.

5. Not using the error notebook

People solve 50 problems but repeat the same mistake on the 51st. If you don't capture the root cause, your brain will default to the old habit under pressure. Your notebook is your personal coach.

6. Overusing formulae, underusing reasoning

If you see a standard formula and plug numbers without thinking, you'll fail on multi-step problems. Before plugging, ask: "Do the conditions for this formula hold here?" (e.g. constant acceleration, ideal circuit, etc.)

7. Cramming new material in the last week

In the final week, do not learn new topics. Consolidate. Re-do your top 10 errors, recall your formula sheet from memory, take one mock, and fix only what breaks. Tapering feels counterintuitive but saves marks.

8. Skipping experiments

"I'll focus on theory first" is a common trap. If Nepal has an experimental round, neglecting it is dangerous. Start error analysis early — 1 hour a week is far better than 0 for months, then 10 hours the night before.

Takeaway

The difference between clearing pre-selection and breaking through to camp is rarely "knowing more". It's usually fewer careless errors, better exam discipline and knowing your own weak spots cold.
