GRAMMAR REVIEW! Can, should, must

Here are some tips on using can, should, and must:

1. CAN - Possibility or ability
Meaning: Shows that something is possible or that someone has the ability to do something.
Usage:
Ability: "I can swim."
Permission: "You can leave early today."
Possibility: "It can get cold at night."

2. SHOULD - Advice or recommendation
Meaning: Suggests what is right, good, or recommended. Not as strong as "must."
Usage:
Advice: "You should eat more vegetables."
Expectation: "The train should arrive at 6 PM."
Mild Obligation: "You should apologize to her."

3. MUST - Strong obligation or necessity
Meaning: Expresses a strong rule, requirement, or necessity. Much stronger than "should."
Usage:
Obligation: "You must wear a seatbelt."
Strong Advice: "You must see that movie - it's amazing!"
Deduction: "She must be tired after that long trip."

DID YOU KNOW?

Unlike many other English proficiency tests, the Cambridge English Qualifications have a separate grammar section.

These are classic proficiency/certification exams (FCE/B2 First, CAE/C1 Advanced, CPE/C2 Proficiency) with a dedicated "Use of English" section that tests grammar and vocabulary directly (e.g., multiple-choice cloze, open cloze, word formation, transformations).

FCE (B2 First) - includes Use of English (grammar + vocabulary)
CAE (C1 Advanced) / CPE (C2 Proficiency) - similar integrated grammar section

The "Use of English" part is explicitly grammar-focused rather than just measuring general comprehension.
