I post questions one day before.

"Everyday I check answers of the questions that I post one day before on the forum" (I mean I post a question today and check it the next day).

Please check.

"Every day I check the answers to questions I have posted on the forum the day before."

There are other possibilities, but this is the one that occurs to me first.

If it's true that you check the answers to the previous day's questions every day, why don't you respond to them?

The first variant that occured to me was "Every day I check the answers to the questions I have posted on the forum the day before." Is it OK?

I do but when I have to go to the hospital or I am not at home then only I don't check.

"Tom's parents check everyday, whether he has been to the school the day before." Is it correct?

I'd like to draw your attention to the following moment. In the UK you're likely to hear "go to hospital" rather than "go to the hospital". I think it's more an American thing. I'm not sure though.

"Every day I check the answers to questions I have posted on the forum the day before."

I'd write Every day I check for answers to the questions I posted on the forum the day before.

I have posted on the forum the day before."

Don't use present perfect with a specific time reference.
I posted on the forum the day before.

It is OK, yes, but it's also fine without 'the'.

"Every day I check the answers to questions I have posted on the forum the day before."

I would say '... I have recently posted on the forum' without 'the day before' if the present perfect is used.

Please check.

What do his parents check every day?

Correction for post#12.

"Tom's parents check every day whether he went to school the day before."

Correction for post#14.

"Tom's parents check everyday whether he went to school the day before."

1. That's not a correction of post #14. It's a correction of post #12.
2. Read posts 13 and 14 again, specifically about your incorrect use of "everyday" (which is an adjective).
