ពាក្យដែលកម្រប្រើ (Low-Frequency Vocabulary)

In C1 English, we upgrade common words to low-frequency words. These are rare, highly specific words used in professional and academic settings.

ពាក្យកម្រប្រើ គឺជាពាក្យដែលគេមិនសូវប្រើក្នុងការនិយាយប្រចាំថ្ងៃ ប៉ុន្តែវាស័ក្តិសមបំផុតសម្រាប់ការប្រឡង IELTS ឬការងារផ្លូវការ។

Hi Sovan! Only if you use them correctly! If you use a rare word in the wrong context (e.g., "I consumed a colossal burger"), the examiner will know you memorized it. Use C1 words when discussing complex topics, not simple daily tasks. psychology

Don't memorize lists! Group them by topic and learn their "collocations" (words they naturally pair with). For example, don't just learn "detrimental"; learn "a detrimental effect on health". link

Not at all! Fluency and clear communication are always the most important things. It is much better to speak fluently with simple B1 vocabulary than to stutter and freeze trying to remember a C1 word! thumb_up
