This was the first time we opened up our in-house

This was the first time we opened up our in-house Mid Year Exam to the public.
Since the schools are not able to conduct Mid Year Exam, we offer ours to anyone who wants to be tested. For free!
The response was overwhelming. Now that we are doing it virtually, we are no longer constrained by venue size!
We are collecting feedback. So far it is very encouraging. All felt that they really learnt something and the session was useful. If it is helpful for students, we may just do it again!

No Mid-Year Exams = No Preparation We're opening

No Mid-Year Exams = No Preparation We're opening up our in-house mid-year exam assessment to the public for FREE!
Join us for the mid-year assessment+coaching session FOC! If you are taking your O level A. math or A level H2 math at the end of the year, you better know your own preparedness now. You still have time to catch up and do something.
All you have to do is to get tested!
Join us for free. No obligation, no gimmick.
Go to www.numberskill.com/mid-year-exam for details.
Hurry! Limited slot and limited time offer!

It has been more than a month since we moved our classes online. The response is nothing short of encouraging.
Survey result has shown that 💯% of our students find the virtual classes effective for their learning.
In fact, a handful of students and parents like it more than in-person lessons and are even asking if these virtual classes will continue after CB is lifted!
We are thankful to our students and parents for their support during this period.
We're also glad that we haven't disappoint them.
As we continuously try to improve the quality of our lessons, we've moved to using Microsoft Teams and Class Notebook for our virtual classes. Many universities are using this platform for their off-site learning. It is definitely more suitable for education than Zoom. We're probably the first and only tuition centre using Teams and Class Notebook for our virtual classes.
As we stay safe, stay healthy and stay at home during this difficult period, our lessons also stay effective!
We're currently having a One-For-One Trial lesson. Join us for two trial lessons for the price of one. Contact us to find out more!

Amid the tuition centre lockdown, our classes have been running as usual albeit online.
Parents and students are happy with what we are able to do. We didn't disrupt our students' lives nor their learning.
Everyone stays safe and stays at home but learning goes on.

We are interviewed by MediaCorp Channel 8 News about the preventive measures we have implemented in view of the covid-19 outbreak.
Besides sanitizing our centre after every class, we are proud to be one of the few tuition centres which already have the capability to record and/or live stream our lessons.
Our students can stay at home and still not miss any lesson if need be.
We are ready. Our students will be ready for the exams too!
