Worst school/college I have ever been to. And I am not kidding.
As someone who was in the top-20 students nationwide in the UK by GCSE grades, I feel like I can convey my thoughts about the school.
The 'immense workload' at Hills Road is a complete myth, provided you have a passion in the subjects you choose. I didn't find it challenging enough, and got dissapointed as a result multiple times. For example in Chemistry I found only a single topic interesting (NMR), whereas in physics there actually was none. I would have found particle and quantum physics interesting had I not been constantly reading the topic for the past 4 years prior to that. Further Maths was a different story, of course, but I was dissapointed there too at times.
The first minus of Hills Road is the mandatory EPQ project. Whilst this was personally no problem for me (I wrote an entire book on killer waves in the ocean), I think most people are unaware of this when they go, or if they are they forget about it. And this project takes a year of lessons in school, so unless you truly are interested you are not going to enjoy this. The biggest letdown of the project was that they barely even cared about the product- they wanted only to see the 'research process'. Whereas the Perse had an internal project qualification offering a Rouse award for an outstanding product, I firmly believe that even if you built an entire robot from scratch, but didn't write enough on the process, you could well get a D or below for your effort in Hills Road. Whereas actually completing my project was fun, I think if I had to choose again I would not have bothered with Hills Road for this reason alone.
The second minus of the school for me was enrichment. Whilst I understand that some or perhaps even most people will disagree with me here, I personally didn't enjoy being forced to do something I didn't really enjoy. The school did have a lot of clubs and societies on offer, but none really appealed to me. Hills Road should have at least made it recommended to prevent people like me from feeling that their time was wasted, that they were being forced to do it and so on.
The third minus is Hills Road in 2019 for some reason had the autumn half-term a week before everyone else did, which decimated my plans to see relatives. Not sure why Hills Road did this.
A massive fourth minus is the way I got treated by a maths teacher. As someone who took the Cambridge maths interview seriously (and ultimately passed it) I started preparing in Autumn 2019. I barely talked to anyone, had no friends and spent my time reading textbooks during the lunch break. I was sending emails to my teachers asking for clarification in a few places. Even asked them a few interview questions I couldn't understand. This ended with one of my teachers standing me up and literally saying in front of the entire class that I would never pass the interview. I never did get to look him in the eyes when I passed.
When the first lockdown happened I got a grade C predicted for me in chemistry. Not matching my abilities at all. One of the tests I was forced to do in the same area where a friendship group was screaming and playing something (note that this was 'chemistry surgery'). When I asked why that was included, I was told rather smugly that 'as scientists we must use all available data' despite the same teacher telling me not to worry about it when I raised my concerns before the lockdown happened, which is when the test was. I was also told that 'it was just a mark' and that 'my teachers are very experienced'. I couldn't tolerate this, and raised it with the head of the department because if this injustice stuck I would miss my chance to go to Cambridge university.
This ridiculous story ended with 3 different teachers apologising to me for this and my predicted grade going up. It was still very bad (I treat an A as a failure for me), but at least it wasn't a C. The next year my maths grade crashed after my teachers included a mark I got from a test I sat very shortly after a family member died, and I wrote more than 3 emails asking for that not to be included for this reason, and each time got a positive response in reply! The same thing happened with onward grades too.
During the coronavirus pandemic I was forced to come back to the school in Autumn 2020. I had to wear an N95 every single day of my time there because I was afraid for my health (I have asthma with landed me in hospital a lot of times, but my concerns were brushed aside). I had regular nightmares too.
Based on the above, I think people should stay clear of this school if they are capable of things like this. It's not worth it.
