• I enjoyed going through the questions! I feel that going  through the questions help me to better understand the process.

• Kind of related to above but besides going through the qns after I do it, I also like going through it before, as it also helps me understand what I should be writing.

• I also enjoyed the clarifications of what I did not know (eg the diagrams)

~ Student, IB6 ACJC, 2025

~ Student, IP4 NYGHS, 2018

I needed a top notch tutor who could do 1 on 1 and not group class because of his national & international sporting commitments and therefore timings. Someone who could really push, motivate & monitor him because I knew he had potential for sterling results. Did a lot of trawling through parent chatgroups and basically got a couple of names. Tried out a few actually and got lucky with you!! We also found out you used to teach JC and competed in running competitions so we knew you would understand him as a sports person.

~ Parent of Student, IBDP Year 6 ACS (I), 2017

1) Very motivational :)

2) The super detailed analyses on my tests / exams :)

~ Student, Sec 4 MGS, 2017

~ Student, JC2 ACJC, 2017

Hi Duncan, the past few months have been a rollercoaster ride but I thank God that He has taught me many things during this time of uncertainty.

I've been accepted to NUS Medicine and will be starting this August.

Thank you once again for your encouragement and counsel. It helped me cling on and continue to persevere in pursuing my dream. Although medicine is overly romanticised, I do believe that this is a career that I will thrive in.

Thank you once again. God Bless.

1) How you always try to test us on our previous concepts learned

2) How you always tell us related extra information that lets us make the connection between Biology and our daily lives, which makes it more interesting

3) Your enthusiasm and interest shown when teaching. Its really infectious!

4) How you are so detailed and patient when we are clarifying our doubts. You make sure that we fully understand it before moving on to the next thing.

I can’t think of anything (for Tutor improvement) because I feel that your way of teaching really suits me a lot! I am really motivated to study Biology because of lessons held with you. I think I am the one who needs to improve and put in more effort instead…haha. x_x

DUNCAN ANG :) 23/09
Thanks for being such an awesome BIOLOGY teacher. Though you only taught us for a short four months, you will be dearly missed by 23/09. Thank you for making your lessons so interesting and engaging with your "PE lessons" at the MPH. Though I have failed the two biology tests, I will work harder and not 辜负你的! Remember us kay :)

P.S. Your smile lights up everyone's day so SMILE MORE :) :D haha!

~ JC1 AJC, 2009

Mr Ang :D

Thanks for all the wonderful lessons. You never fail to make them interesting and we always look forward to Biology tutorials and your lecture. I will remember what you said and work hard to "live up to the time-honoured tradition of Bio-Reps with legendary Bio concepts." GIVE ME FIVE! With that, I wish you a good day.

~ JC1 AJC, 2009

Hi Mr Ang! :)

I really appreciated you and your dedication towards teaching! It is really wonderful to have you as our bio teacher (and also half a PW teacher). You made us always look forward to your lessons! I would remember what you said at the last tutorial to never give up and not afraid of failures! I believe that you indeed made a difference in our lives! Thank you so much and we will definitely miss u! All the best for your future endeavours!

~ JC1 AJC, 2009

Dear Mr Ang,

Thanks for being such an interesting Biology teacher. I think I'm rather lucky for I've got GREAT Bio teachers since my sec school years.  All my Bio teachers are great, but you are GREAT & DIFFERENT. Besides all the biology concepts, you taught  us different ways of learning, through games and those truly useful mindmaps, and also taught me a very important thing in life--STAY POSITIVE!

All the best for all the things for you in the future. I wish you success in your plants-related research and never stop smiling! (you always make us laugh when you put on a smile! :D) Lastly, continue to inspire more people, just like how you inspired us!

23/09

~ JC1 AJC, 2009

MR ANG

thank you for

• making me do concept maps

• feel as though I'm on a roller coaster during your lessons

• surprising me with your interesting and engaging tutorials.

Give me 5!

Mr Ang!

Thank you for your patience and wonderful teaching! You have always been a great teacher, and like a great friend to us! Your smile and laughter always brighten s up our day! Must stay happy everyday :) hearts X333All the best! :)

HELLO MR ANG!!

Before you leave this school, just want to tell you that you have been really a great bio tutor whom I have always looked up to. thanks for everything that you have done for us, including all these concept maps, and not forgetting all the games! :D thanks a lot & you will be missed.

Mr Ang! :D:D:D

Thanks for being such a great bio tutor! & bio tutorial is the tutorial I most look forward to! :D:D:D You've been a very cheerful and caring teacher :) Thanks for all that you have done for us. all the best! 加油!

~ JC1 AJC, 2009

TO: Mr Ang...
Hmm...Not really sure if you are still teaching us next year. Just want to say that I've always enjoyed bio lessons. Perhaps I thought it was interesting  but I believe that the teachers play an impt role too. All my bio teachers were nice & encouraging (and) that includes you! :) Yup. Want to thank you for your efforts & that I really enjoy having your lessons :)

P.S.

• Don't throw! Pls? :)

  • spend 3 hrs on it. All hand-drawn. XD

  • unique & one-of-its-kind design :)

• Yup...there's not enough space in front. :C

~ JC1 AJC, 2009

Mr Ang

He is thin...well muscular, and has this kiddy look. He talks like a machine gun and his poor students learn to adapt to his speed and forever, adapts to anyone's talking speed. He got the ' student give me five' and 'concept map' style that distinguish him form the rest of the teachers. He teaches us to be more pro-active, take more initiative by threatening us with concept maps.  He bonds with the class as if he is one of us and invites special guest like 'spiderman' and 'resident evil'. Learning is fun, enriching and efiicient. May God bless him even if we are not around him and may he remember that 3109 will always love him!

~ JC1 AJC, 2009

MR ANG,

Hey! You've been such a great PD tutor and bio teacher! I will never forget the care and concern you have shown towards us. You have taught me to see failure in a whole new light and for that, I thank you. Even though you were with for for only 2 terms, but you have left a lasting impact on us. I hope you would not forget us, 31/09. I wish you all the best for the future too! Once again, thanks for being the best PD tutor ever! I will definitely miss you (:

~ JC1 AJC, 2009

To Mr Ang, 

It is a blessing to have you as 3109's PDG tutor and most importantly: OUR FUN BIOLOGY TUTOR :)

Many thanks for all the great lessons you provided us with esp. civics lessons. The slideshow you presented during one of the civic was real motivation for me.
"DON'T compare yourself with anyone in the world, if you compare, you're insulting yourself." :D

"EVERY successful story has a painful story. Every painful story has a successful ending.

Bear with the pain and get ready for success! :D

Your patience had made our learning more enjoyable, your presence had also made biology more interesting with those video clip. 

Take care and all the best!

YOU'VE BEEN A GREAT TUTOR

~ JC1 AJC, 2009

To Mr Ang, 

I am so happy to have you as my teacher! For the first biology tutorial lesson, you told us few sets of rules, including doing concept maps if any one of us cannot answer your question. I was thinking: this teacher is so strict to us. Indeed, you have high expectation for all of us. At the same time, you are reasonable, genuine, caring, sometimes humorous. Between you and students in 3109, there are mutual respect and friendship. I really enjoy your lessons. Now, you are leaving. It was a shock to us. However, we cannot do much about it. The only thing I can do is writing this message to you, hoping you have a (memorable) experience with 3109. My classmates and I will appreciate the experience with you forever.

All the way! Mr Ang!

~ JC1 AJC, 2009

To Mr Ang, 

Hello Mr Ang!!! First of all, I would like to thank you for being my teacher for the past few months. I really really enjoy your lessons and jokes. I think you are the only teacher who I have known with the most most number of encouraging words or phrases used each day. I think this is a really good way to motivate the students and make them feel more confident of themselves. I am one of those who have benefitted from your way of teaching. I really would like to thank you for what you have done for our class, the joy and the encouragement.  Maybe after your research you can come back and teach us? Haha...I will definitely remember what you have taught us during civics. I will also try my best to be a good class leader and do my best in all tests. I hope that you will enjoy your research and stay happy always. 31/09 will always remember you.

~ JC1 AJC, 2009

Mr Duncan Ang

It has truly been a wonderful and enriching 3 months with you as our PDG tutor. Although you have only been teaching us for a few months, I find myself being greatly enriched by your teachings, both in biology and character development. You have not only taught me to think more critically, but in different ways and on different levels. You have also influenced me-in so many other ways, enriching my soft skills, and developing me into a mature, more selfless person. I have always thought that the most influential teachers were not those who communicated their philosophies through words, but by deeds. You, Mr Ang, are a prime example of this. Your unyielding patience, guidance, integrity and willingness to lend others a helping hand, together with your warmth and sincerity, make you one of the best teachers I have known and probably will ever know. I truly and deeply appreciate your genuine care and concern, one that I find lacking in so many educators who have the intellectual calibre but not the compassion so necessary to effectively teach. Your willingness to share past experiences with us during civics lessons show your humility, and I like how you infuse humour into your stories to make us laugh. Thank you also for pushing us beyond our limits. At first, we were all sceptical about the concept maps but we later realised that you had only wanted the best for us, and to help us achieve a better understanding of biology concepts. Truly, it worked :) With you, we don't have to worry about boring lessons, because you incorporate different teaching methods to make learn ing more enjoyable. As such, we can always count on you to brighten our day :) Thank you for EVERYTHING!

I'd like to wish you all the best in your future endeavors and areas of passion, that you may have as much passion for them as you did for us.

Keep in touch!

P.S. I hope that you like the box of blessings, and that you will use it to encourage yourself whenever you face obstacles in life. Let it be a constant reminder of the lives you have touched.

~ JC1 AJC, 2009

HAPPY TEACHERS DAY MR ANG!

Hey Mr Ang! Haha I hope you like this postcard. Especially chose it for You :D STRONG MAN.

Anyway, I can't seem to thank you enough. Thank You for encouraging me in times that I failed. Thank You for believing in me that I can do well, You don't know how much it means to me :) You're such an incredible teacher who looks beyond grades and it just makes education more fun and meaningful. Thank you for all Your encouragement sweets (buy new ones!) :) Have a great teachers' day!

~ JC2 AJC, 2008

Dear Sir,

Thank you for your guidance in the past 2 years. Under your imperative tutelage, I’ve benefited immensely not only academically but also in life lessons. Once, you asked why am I “perpetually late” so I’ve make it my New Year resolution this year to be on time everyday. In addition, the nuggets of information you share with us on a regular basis have also broaden our knowledge and instill a sense of awareness in us. Hence to show my appreciation, I made an impulsive decision to write you a poem which I’ve never ever attempted before. I hope you have a good laugh.

----------------------------------------------------------------------------

I chose this special present for I want you to know

That you are essential in our nurture and growth

Reminding us that you are always there

And that you really do care

Keratin is an important component of hair

The tortoise will ultimately win the hare

Biology facts and life lessons you shared

Inspired us not to build castles in the air

However in this unexpected twist of fate

You have to leave which is what we hate

But your memories that are deeply etched

Will be preserved even when we age.

------------------------------------------------------------------------

Good luck to you in your future endeavors.

Yours Sincerely,

Jieying =)
