I did, it was absolutely ideal for us and I don't regret it.
I took 15th May (start of exams) to 15th June, DD's last exam was the 17th but we arranged that DH would clear his workload if the last two June weeks would have to be covered.
DD did GCSEs in 2023, she had burn-out during Covid with undiagnosed ASD/ADHD (she was finally diagnosed autumn of 2023). Nearly all weeks from 2022 onward she had to be collected because of anxiety attacks or was physical sick because of panic at least once a week. Every time DH had to be away for work, I had to work from home full time to enable me to drop everything and collect her.
My work knew about the issues, I disclosed it as soon as the burn-out became clear and already told them in December 2022 that I would apply for parental leave in 2023. The regularity of running off during the day to collect her may also clued them in that something wasn't ok. Even when only DH collected her, I marked it in my calendar in case I needed evidence how bad it was.
Parental leave meant I didn't have to stress with work, could focus on her in the afternoons or collect her from school, she had to attend school until the 2nd week of June when the majority of exams were over, no study leave.
I didn't have to rush home after a day in the office to do dinner and was exhausted myself. DH's job means he has often meetings from 3pm onwards so when she came home it was difficult for her to talk to anyone if DH and I were both working.
Luckily my workplace is extremely family friendly so it wasn't an issue.
If you can and can afford the loss of a month pay I would definitely recommend it.
