Honestly, the biggest thing stopping most students from publishing in reputed journals isn’t lack of intelligence - it’s lack of clarity on what journals actually expect.

From what I’ve seen (and experienced), these are the biggest blockers:

1. Weak problem statement / unclear research gap

Most papers get rejected in the first screening because the “why” of the study is not strong enough.
If the gap isn’t clearly identified, reviewers lose interest instantly.

2. Poor structure and flow

You might have solid data, but if the paper is scattered, repetitive, or unclear, journals won’t take it seriously.
Academic writing is more about organisation than fancy words.

3. Mismatch with journal scope

A lot of students send their paper to the wrong journal and expect a miracle.
Top journals are very strict with scope — even a strong paper can be rejected simply because it doesn’t fit.

4. Lack of novelty (or inability to highlight it)

Sometimes the research is unique, but the novelty isn’t communicated well.
If the contribution isn’t spelled out clearly, reviewers assume there’s nothing new.

5. Weak methodology section

Journals care a LOT about methodology clarity — sampling, instruments, validity, reliability, everything.
This is where many students lose points without even realizing it.

6. Fear of rejection

Many students don’t submit at all because they assume journals are “too tough.”
But honestly, once you understand how the review system works, it becomes much less intimidating.

For anyone feeling stuck, overwhelmed, or confused, getting a bit of mentoring from someone who understands journal expectations can make a huge difference.
I’ve seen students who struggled for months finally get accepted once they had proper guidance.
