SMO Review Sessions & Mock Papers

[This is posted on behalf of Mr Way Tan]

Following the positive response to last year’s SMO review sessions on YouTube (total 14k views and counting!), I’ll be conducting review sessions again for this year’s SMO Round 1. The schedule and links are as follows:

SMO Junior: 1 Jun 3:00pm (https://youtu.be/EP2dXpdD5Nw

SMO Senior: 2 Jun 2:30pm (https://youtu.be/Tw3CLCaLnY8

SMO Open: 2 Jun 6:30pm (https://youtu.be/42LFCwMgTwQ

New this time, I have also written a set of SMO mock papers, which you can find at the links below. It’ll be especially useful if you’ve run out of ‘fresh’ SMO papers to do! Their difficulty should be comparable to the more challenging years of the SMO.

Senior: https://tinyurl.com/smosenior2022

Open: https://tinyurl.com/smoopen2022

I wrote a post on Singapore IMO Team Members' University Destinations here.

Below are the university (undergraduate and postgraduate) destinations of the Singapore IOI team members in the last decade. Top 3 university choices are NUS, MIT and Cambridge. Note that most of the guys have had to serve 2 years of compulsory National Service (NS) after their High School, before joining the University. Those guys and girls with no NS obligation are marked with #.
