Better / Best / More Better / Most Best — Why TOEIC Loves This Trap
The useful grammar point is simple: good has irregular comparison forms — better and best.
When a sentence already uses the comparative better or the superlative best, standard written English does not normally add more or most in front of those forms.
1. The comparison pattern
Good → better → best is an irregular adjective pattern. The comparative form is better; the superlative form is best.
Comparative: better
Use better when one person, thing, result, or situation is judged at a higher level than another reference point.
Example: Our new model is better than the old one.
Superlative: best
Use best when something has the highest level of the quality within the relevant group or context.
Example: She is the best candidate for the job.
Accuracy note: “Better = exactly two things” is too narrow. A comparative expresses a higher degree in a comparison; the comparison can be against another item, an earlier result, an expected standard, or another reference point.
2. Why “more better” and “most best” do not fit here
Better already carries comparative meaning, and best already carries superlative meaning. In ordinary standard-English comparison structures, adding more to better or most to best creates an unnecessary double comparison.
❌ Our new model is more better than the old one.
✅ Our new model is better than the old one.
❌ She is the most best candidate for the job.
✅ She is the best candidate for the job.
❌ His performance was more better than last time.
✅ His performance was better than last time.
MTC check: If better or best already expresses the comparison you need, do not stack another comparative or superlative marker onto it.
3. TOEIC-style self-check
The four-question self-check is retained. Q2 and Q4 have been clarified so each item has one clear answer. Choose the standard-English form that fits each sentence.
Q1.Our new product is ___ than the old version.
Q2.Of all the shortlisted candidates, she is the ___ person for the position.
Q3.His second presentation was ___ than the first.
Q4.Of all the restaurants in the city, this is the ___.
4. The MTC comparison check
1. Look for the relationship
Does the sentence compare one thing with another reference point, or identify the highest item in a group?
2. Remember the irregular forms
good → better → best. You do not build these forms by adding more or most.
3. Use sentence clues
Than often introduces the comparison point. A defined group such as in the city can support a superlative.
4. Do not diagnose from one miss
One wrong answer can be a slip. Look for the same comparison problem across several questions or sessions before treating it as a repeated Learning Block pattern.
Final word: use the form the sentence needs
Better is the comparative of good. Best is the superlative. In ordinary standard written English, more better and most best are not the forms to choose for these comparison structures.
The reliable habit is to identify the comparison first, then choose the existing irregular form instead of adding extra comparison words.
If comparison mistakes keep repeating
A single miss does not prove a wider learning problem. If the same hesitation appears across several Part 5 questions, timed sets, or study sessions, review both the grammar decision and the study pattern behind it.

One comparison rule is not enough practice
This page focuses on one small grammar decision. The MTC TOEIC Grammar Drills give you more chances to choose grammar forms across different Part 5-style sentences, so the rule becomes something you can apply rather than simply recognise.
