Hello livelifefortoday. I qualified as a primary teacher last year. I fell pregnant during the first year of Uni, and did not take a year out so I did two placements whilst DS was still young.
I don't want to put you off , but you've asked for honesty so here's a brief look at what my week looked like as a student teacher.
On weekdays, I would get into school for 7.45am to prepare for the day. Preparing for the day was not a gentle start by any means. I would have one hour to photocopy/set up books/load the mornings interactive whiteboard resources. In one school, I had to make sticky labels with the date and title to stick in 31 books. The title was different for each ability group. It took ages to do and I couldn't do it the night before because the queue at the photocopier was always massive.
At lunch time I would mark spellings (25ish books) and write handwriting tasks in about 8 books each day. I'd then set up for the afternoon. If the afternoon activity was art or PE then I had to forget about eating, getting a drink or going to the toilet. Phonics was after lunch, so I'd set up for that too.
After the last child had been collected half an hour after home time, I would go and mark literacy and numeracy books (60 in total) and make sure my phonics assessments were complete. I'd also tidy the mess left behind from whatever the afternoon activity was.
Sometimes I would get the chance to print resources for the following day, but I'd usually run out of time. I would leave school at 5.45 (that's ten hours spent at school each day).
When I got home I'd have to write reflections and edit the following plans according to the work of the pupils (is if they didn't understand the activity, I would have to change tomorrows lesson). I would do this for phonics, literacy and numeracy. Sometimes I'd spend my evenings making resources at home. Id spend about 3 hours working in the evening, every evening. So that's 13 hours a day, 5 days a week: 65 hours a week.
At the weekend id do lesson plans for literacy, numeracy, science, spellings/phonics, guided reading, 'worship' and a mixture of foundation subjects. I'd spend at least ten hours on lesson planning (an experienced teacher might not take quite as long, but as a student it's painful).
So 75 hours a week at least, and I was still never on top of my workload! That's literally like having two full time jobs.
I used to cry every Sunday evening and at one point I started wishing that somebody would bump into the back of my car on the way to school, just so I wouldn't have to go in!
The observations are horrible. I was a good teacher, but you are never good enough (and experienced teachers will usually feel exactly the same way).
I don't mean to put you off, but as I've only just qualified I thought my experience might be helpful.
Oh, and I haven't gone into teaching.
Good luck with whatever you decide to do.
