Let’s be real—grammar mistakes happen to the best of us. I still remember my freshman year, turning in a paper where I confused “its” and “it’s” about a dozen times. My professor circled every single one, and I wanted to crawl under my desk. But here’s the thing: those little errors can tank your grade, even if your ideas are solid. So, let’s talk about the most common grammar mistakes to avoid, so you can write with confidence.

1. The Apostrophe Apocalypse

This one’s a classic. Its vs. It’s—they sound the same, but they’re totally different. “Its” shows possession (like “the dog wagged its tail”), while “it’s” is a contraction for “it is” or “it has.” A quick trick? Read your sentence aloud and replace “it’s” with “it is.” If it sounds weird, use “its.” Also, watch out for your vs. you’re and their vs. they’re vs. there. These are easy to fix once you know what to look for.

Personal Observation:

I once edited a friend’s essay and found five “your”s where “you’re” belonged. She thanked me later, but I still tease her about it. Don’t let that be you—proofread carefully, or get some get professional help if you’re short on time.

2. Run-On Sentences and Comma Splices

Ever written a sentence that just keeps going and you realize you’re out of breath by the end? That’s a run-on. And a comma splice is when you join two full sentences with just a comma—like this: “I love coffee, it keeps me awake.” That’s a no-go. Fix it by using a period, semicolon, or adding a conjunction (like “because” or “and”).

Sometimes, professional editing can catch these sneaky errors. I’ve used get professional help before a big deadline, and it saved my GPA more than once.

3. Subject-Verb Agreement Slip-Ups

This one trips up a lot of students. Example: “The list of items are on the table.” Nope—it should be “is” because the subject is “list,” not “items.” The key is to ignore the words between the subject and verb. Focus on the main noun. If you’re unsure, try simplifying the sentence in your head.

Relatable Example:

I once wrote “The team are playing well” in a sports article. My professor corrected it to “the team is playing well” (in American English, groups are singular). Lesson learned—check your references!

4. Dangling Modifiers

These are hilarious when they happen to others, but embarrassing when it’s you. Example: “Walking to class, the rain started pouring.” Wait—was the rain walking? Nope. The modifier needs to be next to the thing it’s describing. Fix: “Walking to class, I got caught in the rain.” Simple shift, huge difference.

If grammar isn’t your strong suit, don’t stress. You can always get professional help from pros who know the rules inside out.

5. Overusing Passive Voice

Passive voice isn’t evil, but using it too much makes your writing weak. Compare: “The experiment was conducted by the students” (passive) vs. “The students conducted the experiment” (active). Active voice is clearer and more direct. Save passive for when you really need it (like when the doer is unknown).

Final Thoughts

Grammar doesn’t have to be scary. Start by focusing on these five areas, and your writing will get stronger immediately. Remember, even professors make typos—but being consistent shows you care.
