A short personal review on Onda v820w

There was a sale on Qoo10, that sells a windows 8 (genuine) tablet for $99! Even android tablets usually cost more than that. I thought it was a good deal and ordered 1 for myself to test it out.

It is 8 inch in size, pretty much single hand holdable by me. It is very light too, as it is made mainly out of cheap plastic.


1) Doesn’t work well with all stylus, especially those with rubber tip. I tried Dagi stylus and it worked pretty ok but….

2) The screen gets scratched easily, my Dagi stylus left numerous scratches on the screen. Probably I should have ordered a tempered glass screen protector.

3) Memory space is very little, for 16GB it is sufficient for windows 8 and Office 365. I don’t really like Office 365, so I uninstalled it and installed Office 2013 instead. In the end my memory only left approximately 1 GB. So I had to buy a 64GB micro SD card ($26 from Qoo10) and install other programmes into the SD card.

4) Battery life isn’t that great, watching videos etc probably last around 4 – 5 hours? If is just looking at documents then it should last around 7 – 8 hours.

5) The windows version is in Chinese, so you will need to do switching to English, even so it will not be 100% in English.

6) No usb port, but a micro usb port so you will need an adapter to connect usb items.


1) The screen resolution is pretty good, probably because it is just 8 inch instead of 10 inch and beyond.

2) The processor and 2 GB ram makes running of programmes smoothly. A lot of tablets at this price range only offer 1 GB ram.

3) It’s windows, so you can open and work on office documents without worry about compatibility.

4) I bought a dual OS, means I can switch between android and windows in 1 device.

5) It has a micro HDMI port, which is really useful if you want to project the tablet to an external screen, such as tv or projector while giving a lecture.

In summary, I find it a good buy at $99, as now I can carry a portable windows tablet and do some work while on the go. 8 inch means I can put in a mini bag and easily hand hold it while standing on bus or MRT. If you are looking for a more complete package, i.e. with longer battery life or stylus then maybe Lenovo or Dell tablets would be a better choice, however they also come at a higher price, probably twice of Onda’s price or more.

Tutors provide 2nd opinion, just like doctors and insurance agents

In some ways I find private tutors similar to doctors, in the field of academics. I just want to share an example of how a school teacher have marked a student’s answer in an unfair manner. This is not about the matter of marks but it brings disillusion to the student’s learning.

This question was from 2015 ACJC JC 2 Common Test 1 (H2 Mathematics) on the topic of Permutation and Combination. The question I would like to highlight is Q5(ii).



The marker awarded my tuition student 0 marks, and mentioned “cannot use dumping method”. Based on this I assumed that the school teacher thought that this method was completely wrong and hence no marks awarded. However my student’s method is actually acceptable, just that it is incomplete.

The full solution would be to consider 9 cases (my student wrote 6, missed out 3). The remaining 3 cases are

1) 3 tennis, 1 squash

2) 2 tennis, 2 squash

3) 1 tennis, 3 squash.

I would probably award 1 mark, but that’s not the issue. The student thought that her method was completely wrong and was confused as she cannot see where’s the mistake. She was prepared to “forgo” this method and force herself to accept the teacher’s method which she finds it hard to swallow.

Main reason for incorrect marking by the teacher:

The teachers want to finish marking piles of scripts asap, hence whenever they see a wrong answer they may be tempted to just give a “0” instead of thinking about where and why the mistakes are made. Many failed to realise that at JC level students have their own way of thinking and it is our job (teachers or tutors) to fine tune the methods they are comfortable so that the methods are appropriate and correct, rather than rejecting their ideas (unreasonably) and force them to do things they don’t comprehend.

Nevertheless, P&C is probably the hardest topic to mark for me. There are numerous ways to count and solve a problem, a teacher may not know all of them.

P.S: “Dumping Method”, reminds me of toilet or Yummy Dumpling.

Ethics and values are more important than grades.

Time for a life lesson you will never forget, Amos Yee.

It is fine to want to be famous. But one must do it in an ethical way and responsible way. Some may say he is just a kid but at 17 years old he should be sensible enough to bear consequences for his own actions.

Not sure what will happen to him, I think making him to do many many hours of CIP in public is a better option than simply throw him into boy’s home.

I refused to watch his video as I think it is a waste of my time and an insult to my intelligence. I believe whatever argument he wants to bring out is merely parroting what people have said online, he is not mature enough to even understand local issues.


Just some thoughts whenever I see tuition ads

You can say I am posting this because these are my “rivals”. I just have mixed feelings, probably as a former teacher, when I see these tuition adverts. I believe I am the type of part time tutor that wish for the good of the students and the education system will improve and not just for the sake of money.

I admit that I do collect fees as I need to feed my family too but no matter what I still think there should be ethics maintained in the tuition industry.

I saw this advertisement and a few things come to my mind.


1) What are the OCBC cheques for? Why is money involved?

2) Looking at the uniforms I think it is pretty expected the students from the top JCs should be scoring As (which I cannot see from the certs).



Having current JC lecturers seem to be a very good marketing point to the interested parents. BUT….

What if you are the parent whose child is under these teacher’s care and are not doing so great. Will you feel good that these teachers are spending time earning money and coaching other students, instead of spending more time fulfilling their core duty of nurturing their own school students? I shall assume that the students are not attending their own teachers’ tuition lessons.

When the ministers or MP voice their concerns about current teachers taking tuition job, I believe they have a point. Teachers are complaining that they have too much work to do, not enough rest time, yet how come these teachers still can afford time for earning extra money? My take is that the number of hours is fixed, to allocate time for part time job means something else has been sacrificed, hopefully not at the school’s or students’ expense.

Finally: are they even real current JC lecturers? Parents must ask to view their certificates for verification. There have been cases of tutors faking to be JC lecturers.

Respect is not just about making physical appearance

What matters more is that we continue to take good care of Singapore, carry on the principles of doing what’s best for the country and practice them, pass them on to the next generation.

Visiting him but making a mess is not a form of respect in my opinion. A citizen who never visit him personally at the Parliament House but makes an effort to make Singapore a cleaner place is showing more respect IMO.


To students who fall short of budget to hire professional tutors

NUSTLS approached me 3 weeks ago to ask if I am interested to join in their project on helping Indian students with A level Math as part of charity. I was very interested but the timing does not fit my schedule as my weekends are very very packed.

Nevertheless I thought I should still share this with all of you, especially those who cannot afford the fees charged by tuition centres or private tutors.

I do hope I have the chance to conduct workshops during holidays to help them out.

I really like the phrase ” I see A in U”, if you understand the pun.
