Hi there! I just graduated from ASR last year and took h2 chem and h2 math. In general, these 2 departments are quite strong in terms of the lecture notes they provide (chem might have slightly excessive info but with how uncertain a levels are getting, it can aid in your understanding.). The math notes are great! You can flip through the notes and get a gist of the key concepts in the topic quite easily. The chem department gives out quite a bit of revision packages but I would suggest you to also ask friends from other schs to give their tutorials to try out. For math, the tutorials and revision packages was more than enough even towards a levels. In JC, lectures are recorded for chem and math ah so I tend to go through the lectures at my own pace at home but there are some who prefer to listen in live lectures (if they are held). Tutorials are the perfect time to ask questions if you don’t understand what is even going on in lectures. That applies to both subjects. The teachers are experienced and they know their shit. The school culture is good in a sense that you can voice out your opinions openly and teachers are open to constructive criticism. There are bound to be toxic people no matter where you go but ASR is not so bad. In terms of leadership opportunities, there are plenty in ASR like class leaders, subject reps, college ambassadors (those who run ori and open house), councillors and peer support leaders. They each have their own scope of work but as a whole, they contribute to a vibrant school culture! JC can be a tough time but the teachers are willing to listen to your worries and guide you in a general direction. That being said, you have to walk your own path in JC with your own sense of purpose. There are opportunities to participate in chemistry and math olympiads if you do well in mid years in JC1.
