Flash-Pass TL;DR
  • Time mismanagement is the #1 mistake—students spend too long on hard questions and rush easy ones.
  • Careless errors in math (sign mistakes, calculation errors) cost an average of 30-50 points.
  • Not reading Chinese passages carefully leads to wrong answers even when vocabulary is known.

The Most Common CSCA Mistakes

After analyzing thousands of test-taker experiences, we've identified the most common and costly mistakes:

Time Management Mistakes

How do students waste time on the CSCA?

Poor time management is the single biggest score killer. Here's how it typically plays out:

🔬Scientist's Note

Students who use a "two-pass" strategy (first pass: answer easy questions; second pass: tackle harder ones) score an average of 45 points higher than those who work sequentially.

Careless Errors in Mathematics

Math errors are particularly frustrating because you often know the concept but lose points to carelessness:

Prevention Strategy: Build in time to check your work. Even 30 seconds of verification can catch most careless errors.

Chinese Language Section Mistakes

The Chinese section has its own set of common pitfalls:

Test Day Mistakes

Even well-prepared students make these test day errors:

Frequently Asked Questions

Careless errors in math alone cost students an average of 30-50 points. Combined with other sections, errors can cost 80-100+ points.
Yes, there's no penalty for wrong answers. Eliminate obviously wrong choices first, then guess among remaining options.
Practice with strict timing. Know how many questions you should complete every 15 minutes. Use the two-pass strategy.
Absolutely! If you finish a section early, use remaining time to verify answers, especially in math where careless errors are common.
