I'm Thiwanka from 2022 advanced level batch. I was able to obtain A for chemistry because of the support given by Dulan sir. His teaching methods are well adopted such that the lessons are highly easy to understand and his notes are great inorder to remember the required details of those lessons. His great at all lessons But I have never seen any other teacher who could make inorganic chemistry as easy as dulan sir. Overall learning with dulan sir was one the best learning experiences of a lifetime and I am thankful for the guidance and assistance provided by sir.![]()

I am Githmi ... I am 2022 Al student.untill schools start I didn't join for any tution class. that's because I couldn't able to choose a good tutor. Due to the information I got from leaflets and my elder cousins my mind was muddled to find a good class.but after starting of my school I realized that I really need a tutor.so one of my school friend said about sir dulan. So suddenly at the evening I joined the class with my another friend.there after I got that idea chemistry in not too much harder if I work with the help of sir dulan. but I missed the first two lessons as I joined little bit later. So I joined with 2023 class to recover them. sir Dulan's 2022 Al working system is also very excellent. Due to this pandamic situation also there are no any errors . Alike in the physical classes the good explanation and paper discusses are there in online sessions. I am a advanced level maths student but there are no worries in theory units also . Sir didn't give so long notes. the all notes are in their simplest form . Special points in resource book also giving by him in their simplest form. all of the notes are like short notes which are very useful to study easily in short time . And again I said that sir Dulan's working system is a great attractive system to subject chemistry *So finally I inviting all of u for sir Dulan's 2024 chemistry class . Don't delay to join this class otherwise you also worry like me about missing sessions..... Good luck....*![]()

I'm Eshani Panamulla a former student of musaeus college col-7 who sat for ALs in biology stream. I started my chemistry journey with a well known mass class. But i got to know sir dulan right after my first term in grade 12 from a friend of mine. So i started an individual class with Dulan sir. After few months of the class with dulan sir i stopped my mass class as well because how sir taught was way clearer and easier to grasp than what was done in the mass class. Other students in our class had so many complicated chemistry notes while i had a few note books, short notes, easy-to-refer flow charts and diagrams, which contained everything we needed for the exam. Sir dulan's method of teaching made one stress out of my head. Which gave me time for other two subjects. In 2019 i sat for my examination and got my results as BCC, where my B was for chemistry. Since it was not my target to stop i sat for the second try in 2020. I went to Dulan sir for chemistry in my second try as well. And the results came out with 2As and 1B with an z-score of 1.9445. Where the As were for chemistry and biology. I got selected to Faculty if medicine, University of Moratuwa. A major thanks to dulan sir for the guidance given us in chemistry and also in other subjects as well. I would recommend dulan sir for any brother or sister no matter which level you are in, he will do the best to take you alot of steps further. One of the best teachers i've come across my AL journey and and the best chem teacher everr ❤️❤️![]()

Dulan sir, in my opinion is one of the best chemistry teachers. If you want your ALs to be well organized and thoroughly sticked up to the syllabus, Dulan sir would be the finest teacher! If you want your notes to be simple, creative, attractive and in full detail, sir is the best. I can't even believe how sir compress the notes in such a perfect manner! Nothing is missed. The other advantage you'll have once you join with sir is that you'll have an amazing paper class every week! Full of knowledge and experience will you gain throughout the journey. A highly dedicated work with sir would cost you more than an "A". The online classes are still efficient as physical classes, no difference. Sir is very flexible, talented and perfect! You'll never get tired of this class. I joined to the 2023 batch since I've missed the first few lessons as I was doing London OLs. I was using calculators since I was in grade 7 in my school. Being afraid to start local ALs, I never thought I could manage the maths part. But sir even shows how we can compress and simplify difficult maths where little by little I started becoming more confident with myself. So I would highly recommend you sir Dulan. You'll realize the difference once you start working with him.![]()

Initially I wasn't interested on chemistry, sir u made this subject really awesome by teaching through short notes and some special revision programmes. Not only subject matters got a lot of important stuff for our lives too. Finally Thanks a lot for everything Sir 🙏❤
