I was sitting in a quiet exam hall last Tuesday, the only sound the frantic scratching of pens, when I saw it again. A student, clearly brilliant and highly motivated, wrote: “She is more talented as her sister.” I felt that familiar, sharp pang of frustration in my chest. It’s a tiny slip, but in a high-stakes exam, it’s a loud, red flag that tells the examiner you haven’t mastered the basics. Most textbooks will give you pages of dense, theoretical fluff on comparative structures, but they fail to address the real-world confusion of how to compare with as and than in a way that actually sticks.
I’m not here to give you a lecture on linguistic theory or drown you in academic jargon. My goal is much simpler: I want to help you stop making the exact same mistakes that are currently bleeding your marks dry. I am going to show you the precise, practical rules for how to compare with as and than so that these patterns become second nature. We are going to turn these shaky guesses into reliable habits, ensuring your grammar is as precise as it is professional.

The Equality Trap Using Asas for Equality Correctly
Now, let’s talk about the “Equality Trap.” This is where I see so many of my students stumble, even those with advanced levels. When you want to say two things are the same, you use using as…as for equality. It sounds simple, right? But the mistake usually happens when the pressure of the exam clock starts ticking. I often see students try to sneak a comparative adjective into the middle of the structure—writing something like “as taller as”—instead of sticking to the base form. Remember, the structure is rigid: as + adjective + as. If you deviate from this, you aren’t just making a small slip; you are failing to demonstrate the basic grammatical structures for comparison that examiners expect.
It’s a matter of habit. If you haven’t practiced the rhythm of the sentence, your brain will default to the more “active” sounding comparative degree in English grammar. You’ll find yourself reaching for -er or more because it feels more natural in the moment, but that is exactly how you bleed marks. Stay disciplined. Treat the as…as construction like a musical phrase in my choir; if one note is out of place, the whole harmony is ruined.
Common Mistakes With Than and as That Cost You Points
Now, let’s look at the actual damage. I see it in almost every writing paper I grade: students trying to use “as” when they should be using “than,” or vice versa. It’s a classic error in grammatical structures for comparison. For instance, you’ll see someone write, “He is as taller than me.” No. That’s a collision of two different rules. You either use the as…as structure for equality or the comparative adjective followed by “than” for difference. Mixing them doesn’t just look messy; it signals to the examiner that you haven’t mastered the basics.
Another frequent slip-up involves the comparative degree in English grammar regarding long adjectives. I often catch students saying “more better” or “more faster.” This is a double comparative, and it’s a quick way to lose points. If you are using a comparative adjective, you don’t need “more” if the adjective already has an “-er” ending. Stick to the rules: if it’s a short word, add the suffix; if it’s a long word, use “more.” Don’t let these small, repetitive slips bleed your score dry.
My Golden Rules for Avoiding the Comparison Pitfall
- Stop trying to be fancy with ‘than’ when you mean equality. If you are saying two things are the same, you must use the ‘as…as’ sandwich. I see students write “as tall than him” all the time in my advanced classes—it’s a direct hit to your grammar score.
- Watch your adjectives. When you use ‘as…as’, the adjective in the middle must be in its base form. It’s “as big as,” not “as bigger as.” I know, it feels counterintuitive when you’re rushing, but that’s exactly where the marks slip away.
- Remember that ‘than’ is for inequality. If one thing is more or less than another, ‘than’ is your only friend. You wouldn’t say “more better as,” would you? No, it’s “better than.” Keep the comparative forms with ‘than’ and the base forms with ‘as’.
- Don’t forget the second ‘as’. It’s easy to drop the final ‘as’ when you’re nervous during a writing exam. “He is as tall the brother” is a broken sentence. It has to be “as tall as the brother.” It’s a structural requirement, not an option.
- Check your pronouns at the end of the comparison. In formal exam English, “He is taller than me” is common in speech, but “He is taller than I (am)” is what the examiners are looking for. If you want to play it safe and secure those top marks, use the subject pronoun.
Final Thoughts Before You Step Into the Exam Room
Let’s recap so you don’t walk into that hall with these errors still lurking in your subconscious. Remember, if you are talking about things that are equal, you must use the as…as structure—never try to sneak a ‘than’ in there. Conversely, the moment you introduce a difference between two things, ‘than’ is your only friend. I see so many students try to use ‘as’ for comparisons of inequality, and it is a waste of easy marks. Keep your eyes on the structure: equality gets ‘as’, difference gets ‘than’. It sounds simple, but in the heat of an exam, these habits are what will make or break your score.
I know how daunting it feels to sit for these exams again, especially when you feel like you’ve forgotten the basics. But please, believe me when I say that mastering these small details is what separates a passing grade from a high score. You aren’t just learning grammar; you are training your brain to stop making the mistakes that cost you points. Treat these rules like a musical score—once you internalize the pattern, you won’t even have to think about it. You have the knowledge; now, you just need the discipline of habit. You can do this.
Frequently Asked Questions
If I'm using "as…as," do I still need to worry about whether the adjective is a short or long one?
The short answer? No. This is one of those areas where English actually becomes quite predictable, which should be a relief. When you use the “as…as” structure, the adjective stays in its base form. You don’t need to worry about syllables or adding “-er.” It’s “as tall as” and “as expensive as.” The rules for comparative adjectives—the ones that usually trip you up—simply don’t apply here. Keep it simple.
I keep seeing "more as" in some texts—is that actually a mistake, or am I just overthinking it?
You aren’t overthinking it; your instincts are spot on. “More as” is almost always a mistake in exam English. It’s a classic hybrid error where a student starts a comparative structure with “more” but forgets to switch to “than.” Unless you are describing a specific role—like “acting more as a mentor than a boss”—it’s a red flag. If you’re comparing qualities, stick to the rules: use “more [adjective] than.” Don’t let a slip-up like that bleed your marks dry.
When I'm comparing two things with "than," do I have to include the second subject, like "than him," or is "than he" the only way to stay safe for the exam?
Here is the truth: if you want to play it safe for the examiners, use “than he.” It feels formal, perhaps even a bit stiff, but it’s grammatically bulletproof because it’s short for “than he is.” In casual speech, everyone says “than him,” but in an exam, that’s a gamble. Don’t let a tiny pronoun slip cost you a mark. Stick to the subject pronoun—”than he,” “than she,” “than I”—and you’re golden.
