What time is it? What time is it?

*Option to capitalize titles

This sets me free! This sets me free!

Ok to me.

This sets meI feel so free! I feel so free!

To me, "this sets me free" doesn't sound like the correct phrase to use if you're referring to the activities in the previous sentence. "This sets me free" would probably refer to you finishing your work, which was mentioned earlier and doesn't seem like a proper conclusion if you put it here. My interpretation was that you felt free to do what you wanted, so that's why I changed it to "I feel so free."

This sets memakes me feel free! This makes me feel free!

Right now, it is 7 pm at the weekend. Right now, it is 7 pm at the weekend.

Right now it is 7 pm atin the weekend. Right now it is 7 pm in the weekend.

*to me "in the weekend" seems more natural. But check others as well.

Right now it is 7 pm aton the weekend. Right now it is 7 pm on the weekend.

Right now, it is 7 pm aton the weekend. Right now, it is 7 pm on the weekend.

When you're starting a sentence with a time, add a comma after that time (ex: "after I went to the store," "at midnight," "when I was younger,") not sure if this is too helpful sorry "On the weekend" is the correct phrasing, also is used for "on the [day]" but I'm not sure if you already knew that

Right now, it is 7 pm at.m. on the weekend. Right now, it is 7 p.m. on the weekend.

I've already done today'smy English study andfor today and now, I can do whatever I want to do. I've already done my English study for today and now, I can do whatever I want to do.

I've already done today's English study andies so now I can do what I want to do. I've already done today's English studies so now I can do what I want to do.

Better :"so now" meaning therefore you have time to do what you want.

I've already done today's English study andso now I can do what I want (to do). I've already done today's English study so now I can do what I want (to do).

I've already done today'smy English study for today, and I can do what I want to do. I've already done my English study for today, and I can do what I want to do.

"Today's English study" sounds unnatural "I can do what I want to do" is correct enough not for me to change, but to make it sound better you could change it to "I'm free to do what I want" or "I can do what I want" (I recommend this one less)
