When do I use far, much or slightly with comparatives in B2 First?

In B2 First, all three modify comparatives, but they don't express the same intensity. Far and much signal a big difference: far better, much easier. Slightly signals a small one: slightly more expensive. In Part 1 you're often given several plausible options, and the mistake isn't recognising the comparative — it's choosing an intensifier that doesn't fit the meaning of the context.

Can you say very better in B2 First?

No. In standard English you don't put very before a comparative like better, worse, more interesting or less useful. In B2 First this slip is common, because very feels like the natural way to intensify and the instinct turns "much better" into "very better". In the exam you need structures like much better, far worse, slightly more difficult or a lot more effective.

What kind of trap does Cambridge set with intensified comparatives in Part 1?

The typical Part 1 trap isn't only grammatical — it's lexical and semantic. Several options can look like "intensity" words, but only one matches the real degree of difference. If the text describes a small improvement, slightly works; if it presents a strong contrast, far or much fit better. They also penalise unnatural combinations, such as very better or strongly cheaper.

Do far and much mean the same thing before comparatives?

Often yes, because both can reinforce comparatives: far more useful, much more useful. But in the exam you shouldn't think only about meaning — you have to think about natural collocation. Some wrong options aren't impossible in sense, just unidiomatic or simply incorrect in that gap. In Part 1, Cambridge exploits exactly that: you grasp the general idea but miss the exact combination.

How do I tell whether a B2 First gap wants an ordinary comparative or a modifier of comparison?

Check whether a comparative already appears in the sentence: better, worse, more, less, easier, more effective. If the gap comes before that form, they're probably after a modifier like much, far or slightly. In Part 1, the key is reading the intensity of the context: is the change minimal, clear or very marked? That semantic decision is usually what separates the correct option from the distractors.

Where it appears in the exam

Cambridge format example

The second design was a bit cheaper than the first.
SLIGHTLY
The second design was · than the first.

The student restructures the sentence using the keyword

Answer: slightly cheaper. 'Slightly' signals a minimal difference before the comparative. The classic error is using 'a little bit' out of position or reaching for 'few', neither of which modifies a comparative cleanly.

What is it?

This competency is about modifying a comparative to say how much bigger, smaller, better or worse something is: much better, far more useful, slightly cheaper. The instinct is to reach for a general intensity word, but in English not every intensifier works: you can't say very better, even though very feels like the obvious way to say it.

Why it matters in the exam

In B2 First it appears above all in Part 1, where several options look compatible because they all express intensity. If you pick a modifier that doesn't combine well with the comparative, you lose the mark even though you understood the text perfectly.

The cognitive trap

Instinct

"Your instinct reaches for very + comparative: "This method is very better than the last one.""

very is the all-purpose intensifier you learned first, so the brain applies it everywhere — including in front of comparatives, where it doesn't belong. The reflex is to mark intensity with the most familiar word rather than the one the structure actually allows.

Rule

"This method is much better than the previous one," not "very better".

In English, a comparative like better doesn't usually accept very. It needs a modifier that's compatible with comparatives, such as much, far or slightly.

Recognition pattern

Which comparison modifier do I use?

Does the sentence already contain a comparative like better, worse, more, less, higher or cheaper?

SÍ

Do you want to express a small difference?

SÍ

Use slightly + comparative: slightly better, slightly more expensive.

NO

If the difference is clear or big, use much or far + comparative: much better, far less useful.

NO

This competency doesn't apply: with no comparative, don't use far/much/slightly as a modifier of comparison by default.

In the exam, look for the key signal first. The answer follows.

Signals that decide the option for you

Signal Form

Gap right before better / worse Use a comparative modifier like much or far

"The new timetable is much better for students who travel long distances."

Signal Form

Gap before more + adjective Think far / much / slightly depending on the intensity

"After the campaign, local residents became far more aware of the problem."

Signal Form

Context with a small, limited or barely visible change Slightly usually fits

"The revised design was slightly cheaper to produce."

Signal Form

Context with a strong contrast: beyond expectations, a clear improvement, a major difference Far or much usually fits

"The practical workshop was far more effective than the booklet."

Signal Form

Option with very before a comparative Rule it out in standard exam English

"Much better" is correct, not "very better".

The errors that Cambridge punishes

Wrong

"The new system is very easier to use than the old one."

Cambridge penalises it because very doesn't modify comparatives like easier.

Right

"The new system is much easier to use than the old one."

Much sits naturally before a comparative to mark a clear difference.

Wrong

"Students were too more interested after the project began."

Too doesn't work here as a simple comparative intensifier; the structure is incorrect.

Right

"Students were far more interested after the project began."

Far reinforces more interested and expresses a big difference, very typical in exam texts.

Wrong

"The second option is few cheaper than the first."

Few can't modify cheaper. It's an error of grammatical category, reaching for a quantity word where a comparative modifier is needed.

Right

"The second option is slightly cheaper than the first."

Slightly signals a small, precise difference — exactly the nuance many exam sentences need.

Wrong

"This approach is very less effective in crowded areas."

Very less is a combination not accepted in standard exam English.

Right

"This approach is far less effective in crowded areas."

Far can also modify less + adjective to intensify a negative comparison.

The learner's short circuit

Analyse the trap by exam format

Part 1 — Multiple Choice Cloze

After taking part in the recycling project, the teenagers became 1 more interested in environmental issues than their teachers had expected.

A very ← tu instinto

B far ✓ correcta

C deeply

D fully

Seeing 'more interested', you activate the general idea of intensity and reach for very as the most familiar intensity word. But the gap doesn't want 'just any intensity': it wants a modifier that can go before a comparative (more interested). Far works because it reinforces a big difference; very can't modify that comparative.

When every option looks like an intensifier

In Part 1, the difficulty isn't spotting the comparative, but knowing which words can actually modify it. Cambridge mixes common adverbs with options that sound natural to the ear yet don't fit a comparative structure.

Strategy

First locate the full comparative: better, worse, more + adjective, less + adjective. Then ask yourself: "does the sentence describe a big or a small difference?" Only then choose between far/much and slightly; don't default to very out of habit.
