the comma helps combine an independent and dependent clause here

To be honest, thisese three days wasere really hard tofor me. To be honest, these three days were really hard for me.

To be honest, thisese three days wasere really hard tofor me. To be honest, these three days were really hard for me.

Three = plural -> these, were

To be honest, thisese three days wasere really hard tofor me. To be honest, these three days were really hard for me.

if the thing is plural, it's "were" if it is a single one, then it's "was" the verb applies to the plural noun "days," so it's "were"

To be honest thisese three days wasere really hard tofor me. To be honest these three days were really hard for me.

I used to sleep a lot, but with this challenge I have to wake up earlier because I wastestudy for around 5 hours to study(a day). I used to sleep a lot, but with this challenge I have to wake up earlier because I study for around 5 hours (a day).

or: "...wake up earlier because I take around 5 hours (a day) to study/for studying." "...take...for study(ing)." - Not wrong, but sounds a little awkward, especially with 'study/studying' being at the end of a sentence' "...take...to study." - Connotation is a little negative. Implies that studying is something that requires 5 hours and the speaker is helpless to change it and doesn't like it. Similar tone to: "I have to study for a whole 5 hours a day." (tone: frustrated, upset).

I used to sleep a lot, but with this challenge, I have to wake up earlier because I wastespend around 5 hours to study. I used to sleep a lot, but with this challenge, I have to wake up earlier because I spend around 5 hours to study.

"Wasting" time means nothing of value was gained (it is negative in meaning). Studying is an excellent use of your time, so I would say "spend" or "pass" time.

I used to sleep a lot, but with this challenge I have to wake up earlier because I wastespend around 5 hours to study. I used to sleep a lot, but with this challenge I have to wake up earlier because I spend around 5 hours to study.

There could also be a comma placed after "challenge," but it isn't needed for readability. The comma before the conjunction "but" is necessary to combine the two main clauses. Also, "waste" implies that you don't believe in what you are doing, while "spend" avoids that issue

I used to sleep a lot but with this challenge I have to wake up earlier because I wastestudy for around 5 hours to study. I used to sleep a lot but with this challenge I have to wake up earlier because I study for around 5 hours.

I want to start to work after this week. I want to start work after this week.

I want to start to work after this week. I want to start to work after this week.

This is fine, but a more natural alternative would be "I want to start working next week." Both are a little ambiguous, though, as we don't know what work you are referring to (e.g., it could be work at a job, work in your home, work on your studies).

I want to start to work after this week.for 4-6 hours per day after this week, so I will not have much free time. I want to start to work for 4-6 hours per day after this week, so I will not have much free time.

I combined three sentences here, since they were short and covered the same topic. Such a revision isn't entirely obligatory, but creatively combining short sentences about similar ideas can improve reader engagement. Also, it is "much" free time, as "many" refers to a plural thing.

WThe work will take 4-6 hours. The work will take 4-6 hours.

Work will take 4-6 hours.

So I will not have manyuch free time. So I will not have much free time.

Combine with previous sentence: "Work will take four-to-six hours, so I will not have much free time." - MUCH more natural.

So I will not have manyuch free time. So I will not have much free time.

"Many" is for things that are discrete and countable (many apples). Things that are considered difficult to count need "much" instead (much sand, much time).

So I will not have many free time.

So I will not have manyuch free time. So I will not have much free time.

Next I choose to watch a serial. Next I chose to watch a serial.

Past tense. If you meant present tense, "Next, I'm going to choose a serial to watch." or "Next, I decided on a serial to watch." "Next, I watched a serial." "Then I chose a serial to watch for next time." (The last sentence implies that you didn't watch the show yet, but you will next time you study.) "serial" is not wrong, but is most commonly used to specifically describe the genre of show the includes things like soap operas, CSI, or other "daytime drama" TV. You can use "show" or "TV series" or just "series" for a more general word, if that's not what you meant. (Note: "series" can also apply to book series.)

NextThen I choose to watch a show/seriales. Then I chose to watch a show/series.

"Next" is better reserved for speaking about the future. For recounting a story, stick to "then." Serial is an adjective; what you mean is series. You can also use the general term "show" which can be basically any TV program that isn't a movie or the news.

Next, I choose to watch a seriales. Next, I chose to watch a series.

Since it is past tense, it's "chose." Also, a TV show with multiple episodes is usually referred to as "a series."

Next I choose to watched a serial. Next I watched a serial.
