Difference between 'tips on study' and 'tips at study'?

Question

I am confused between

Today i would like to give you tips on study

and

Today i would like to give you tips at study

Can anyone explain which one should i use.

Answer 1

Tips on is what is more commonly said in the US in my opinion.

Can anyone give me some tips on how to study English more efficiently?

Answer 2

If you want to know what phrase is idiomatically the most common, it wouldn't be either of them.

The most common would be:

Today, I would like to give you study tips.

You could also use:

Today, I would like to give you tips on how to study.
Today, I would like to give you tips on studying.

At least in terms of writing, you can see this from Google Books Ngram Viewer:

Notice the frequency of the variations, and the fact that where a preposition is used, it's on, not at. (And I actually queried tips at how, not just tips at how to study, and got no hits for anything.)

Answer 3

According to Oxford's advanced learner's dictionary
tips on sth/tips for sth/tips for/on doing sth are acceptable
