Results and Reflection

2020 was a challenging year which forced students and educators to adopt changes to cope. The latest results (83% A/B; 6 in 10 scoring As) not only point to the strength of the students’ characters, but also to the potential that online tuition holds.

Mr Koh’s message to students

To all graduates, I’ve received many celebratory messages and I feel your happiness as well. At the same time, I know some of you are disappointed at not having met your goals. If you belong to the 2nd category, I just want you to know that incidents like this that chip away at your achievements now are not a sign of failure, but building blocks that give rise to a more resilient you. The Covid episode has shown us that there is no career that brings guaranteed success or red-carpet prestige.

As you still have a long road ahead of you, I hope you can be easier on yourself and allow yourself to stumble and falter. Sometimes, taking one step back from your aspirations is a step forward.  It’s like planting rice. The farmer starts from the position furthest away (as far as his/her hand can reach) and inserts the stalks inwards one stalk at a time. It looks like you’re retracting but you’re filling in the gaps one step at a time. Every step is a learning process so make the best out of it. Even a less than impressive result can be spun into a good story (e.g. challenges u faced + how you fought back and made good over time) to showcase your strengths during the interview process. In short, you are young and you are endowed with a good foundation. You can go very far as long as you don’t let setbacks get you down. Hold your head high and continue to work hard. I am very proud of every one of you and I hope you will feel the same about yourself.

Online classes

Since switching to online sessions in Mar 2020, we have not gone back to physical classes. Instead, we have two sessions every week (i.e. converting travelling time saved into extra sessions) and face-to-face consultation sessions on an individual or small-group basis. This arrangement has produced encouraging results. Feedback from the graduating batch highlighted the following:

  1. I have attended both physical and online classes with Mr Koh, and to be honest, I have found the online zoom lessons to be more helpful in my learning. On zoom, I felt I had greater liberty to ask any questions on my mind and could participate more in classes also, which helped to reinforce the concepts, and correct any misconceptions I may have had. Since zoom has a private message function, I felt that i could ask him questions without feeling embarrassed. Furthermore, I am able to rewatch many of the recordings of the lessons to simply refresh my memory or reinforce certain concepts.” – Faith (HCI – A in Econs)
  2. I started online lessons close towards the second half of my J2 year and immediately found classes extremely helpful with Mr Koh immediately sending previous lesson videos on topics I had most trouble in. With lessons being online, my learning for each week was not confined to the lesson agenda for the week as I could easily request videos about other topics or answering techniques previously discussed. With lessons being recorded, it made learning much more efficient as I could rewatch the lesson on my own time when I am less tired and more focused, and change the speed of the video to my liking.” – Natashmin (RI – A in Econs)
  3. I appreciate your live online lessons so much (they’re convenient, engaging, and comfortable). Your YouTube videos also greatly help students who joined at any time to catch up with whatever they’ve missed out on. I regularly viewed your recorded videos from previous lessons to keep in touch with Econs, allowing me to review and recall what I’ve learnt.” – Li Xin (HCI – A in Econs)
  4. Online classes were conducted very smoothly and it allowed me to save on the travelling time. I enjoyed the classes as we could ask questions easily without feeling so scared or shy.” – Andrea (HCI – A in Econs)
  5. After shifting to online lessons, he allowed us to attend J1 classes to recap our J1 content and even provided double the lessons weekly nearer to A Levels without charging extra fees so that we were able to get more revision. Fearing that online lessons may affect our learning, he took the effort to open up consultation lessons for us to ask questions or review our work before giving us individualised comments and areas to work on.” – Jianhao (NJC – A in Econs)

Given the encouraging results our online classes have produced, we will be continuing with online classes for all students. The switch to online classes is also a good chance for students to hone their working-from-home ability as it is likely to be a key part of their work routine in future.

Something new is coming your way in 2021

We switched to online tuition classes in 2020 in view of the Covid-19 disruptions. Results were highly encouraging. Students gave positive feedback on learning through our online platforms. Many found video recordings useful and were able to review recordings at their own pace. Students who were previously less vocal during physical classes were also observed to ask Mr Koh more questions through Zoom’s chat function or via WhatsApp during and after the session. This allowed their doubts to be promptly addressed.

More importantly, with time saved commuting to our centre for lessons, students were willing and able to commit to additional classes to prepare them for upcoming assessments. This allowed us more time to run through students’ queries and to drill and fine-tune answering techniques to help students stay ahead. We are of the view that these benefits remain tangible and significant even in a post-Covid environment. Hence, making additional weekly lessons (at no extra charge) a key feature of Mr Koh’s Economics tuition classes, we are offering pure online lessons in 2021.

Feb 2019: A Level results are out! Congratulations to students who have done well. For students who have performed below expectations in their overall results, it is important to realise that things may not always go smoothly in life. Acceptance and moving ahead (thus demonstrating resiliency) is important. More importantly, have no doubt that the doors have not closed on you. Life is a long journey and you won’t truly know who will stay ahead until at least a few decades from now!
