Monday is the start of a big week for some of you - it's the start of the Sats tests.
Not all of you have to take them, but lots of 11-year-olds in England will be having their reading, writing, maths and science skills put to the test.
We want to know what you think about the exams. Are you ready for them and don't feel that bothered? Or are you feeling the pressure?
Have you any tips on staying calm you want to share?
Perhaps you have worked really hard to prepare for them and you're looking forward to getting them over with.
Unfortunately this topic is now closed but there are Comments pages on other subjects on the main Chat index.

Millie, 12, Devon, England

Lauren, 11, Worcestershire, England

Molly, 10, Gloucestershire, England

"I am not that worried about Sats because I have a lot of support from friends, family and teachers."
Maria, 11, London, England
"I'm not at all bothered with Sats. They are incredibly boring and extremely frustrating. Ever since Christmas all we have been doing is revising, which is completely unfair. I'm not at all concerned with my actual mark. They give us less time to actually learn something."
William, 11, Cumbria, England
"I actually think Sats are a bit easy!"
Melissa, 11, Norfolk, England

Robbie, 12, London, England
"I am 100% relaxed about Sats. But revision is 100% BORING! At school too much pressure is put on children when the results should be celebrated, you've done the best you could. So you should think of them as an achievement!"
Abbie, 11, London, England
"You should be able to rely on what you have been taught and try not to worry. These exams are important but if you fail it doesn't mean you are going to have a bad job when you're older. Just do your best and remember it is a personal achievement."
Issey, 14, Wiltshire, England

Rosie, 11, England
"I did my Sats last year and they are OK. I admit when you sit at your desk with the paper in front of you it is a bit scary, but that is the worst bit. Once you open the paper it it fine."

"I think Sats help teachers understand our ability in school and although they might be a bit challenging they are worth a try!"
Tahmina, 11, Luton, England

Charlotte, 11, Liverpool, England
"I am taking my Sats this year and I actually like Sats and think it helps you work at your hardest. The Sats results won't make much of a difference to the rest of your life."
Megan, 11, England
"I was not scared of the science because I find science easy but I am scared of maths and English because I'm bad at them."
Vaughan, 11, Oxfordshire, England
"I am not worried about Sats at all because it only covers a minor proportion of all the things you do."
Tom, 11, Brighton, England
"I really hate Sats. I wish they could just scrap them. In our school, they usually take the exams in the hall but this year we have to take them in the classroom and it is really claustrophobic. I can't wait until they finish!"
Kate, 11, Dorset, England
"I feel good at home but when I'm at school I feel under pressure and I'm worried."

"Everyone is nervous about Sats, that's just normal. But Sats are about doing your best so I hope I can achieve that!"
Ella, 10, Milton Keynes, England

Dominic, 11, Newcastle, England
"I've had revision books and revised online because the teachers tell us to and it's stressing me out and others in my class. My mum tells me not to stress out"
Lauren, 11, Lancaster, England
"I'm not scared at all, the science tests today were quite easy and I'm pretty confident. It's not fair that next year there probably wont be a science test!"

Noora, 10, Oxford, England
"I think Sats are ok because they're not that hard for me and everyone in my class."
Tahmina, 10, London, England
"I don't see why we have to do Sats because kid in Wales don't do them. Also when you go to your secondary school you get re-tested. I think they are useful because they give kids something to work and revise for but they should ALL be scrapped!"
Rachel, 11, Liverpool, England
"I feel really scared even though I usually get high marks. I think the pressure might get the better of me."

"I'm really enjoying Sats week - we do tests in the morning and rounders in the afternoon - it's heaps better than a normal week! I'm hoping to do well in all my papers and get good results. I've been revising so fingers crossed! Good luck to everyone else doing Sats, work hard and have fun!"
Liv, 11, Leicester, England
"I'm not going to worry about Sats because they're just like a normal test! I know that I have enough knowledge to do it!
Amy, 11, Southampton, England
"At my school we have done a lot of practise tests which didn't really pile on pressure and I got really good results but now that the real Sats are here I feel I have a lot of pressure on me to do well. I am a bit worried but I know all i can do is try my hardest!"

"I feel stressed at home but when I go school I feel perfectly fine."
Nadia, 11, Slough, England
"I think Sats put kids under pressure like I am because you have to work really hard and people have high expectations of you. Also if you don't reach them it's upsetting."
Laura, 11, Nottingham, England
"Last year I thought Sats were really big but they were easy. If you're doing Sats don't worry!! It's so unfair that my sister doesn't have to do her science Sats!"
Susan, 12, Norwich, England
"I did Sats last year I thought they'd be absolutely terrifying. But when I did do them they were fine. So I wouldn't be worried. So long as you revise you should be fine!"
Emily, 11, Nottinghamshire, England
"I don't see why they need to scrap them, and why everyone complains and stresses over them."

"Our school is doing a free breakfast club so that everyone has brain food. I think it's a really good idea."

"Sats are frustrating and dreadfully boring. Revise, revise, revise! I am a bit nervous about the reading exam - it's far too long. But the pressure is over once you're doing it because then it's all so easy. It's revising for it that is the hard bit really. Good luck though!"
Shara, 11, London, England
"We have been under of a lot of pressure to do well in my Sats - but the science test today was ok. My school is going to keep doing Sats tests even if the government say we don't have to. When Sats are over though we are going to have loads of fun and have a party and go to the cinema."

"Well, I am worried a little bit about them because what if I get stuck on a question? I don't know if the teacher will help me. My plan is to not feel stressed because it will all be over soon - and it's unfair that my friends in year 5 aren't doing them!"
