I am a student (J1) from EJC who has attended the H2 Math (Jay), and Chemistry (Jay Jae) classes at JSA. I honestly feel that the classes by them are actually a lot more organised and prepared compared to the tutorials that are in school. Even though they are online, personally, I found myself constantly focused and enjoyed because they always keep their classes interactive through polls, etc

i'm a j1 student at asrjc & i attended JSA's H2 chem and math classes ! my tutors were Jay Jae and Jay respectively. Their explanations are very concise and easy to understand. The questions they give ask really test my learning, compared to school questions which answers can be copied from the notes. The online lessons are very engaging and the break between the 2 hours really helped me focus !

I'm a J1 from NYJC that attended JSA's H2 chem lessons conducted by Jay Jae. Compared to my prior tuition experience, Jay Jae was really engaging and he helped break down concepts until I was able to understand. The the teacher's lingo was also really funny LOL which made me enjoy watching the lessons 😊 You should join JSA because you'll defo see an improvement in grades eith these tutors!!

I am a student from ejc who have attended H2 math and chem classes by Jay and Jay Jae respectively. The classes are more comprehensive and move at a slower pace compared to my school’s tutorials, which significantly helped me understand the subjects better. I highly recommend people to join these classes, as the tutors are patient and very friendly!

i am a current student with JSA in j2 in JPJC. i take h2 chem classes with JSA by jae jay. in my opinion, the notes given by the jayjae are extremely concise and straight to the key ideas needed for your A lvl, the questions he give are way more challenging than those taught in school that allow my chem grades to jump from E in wa1(in j1) to an A in promos with his help!!

i just graduated NYJC in 2024 with 90RP!! I was a student in justscorea's chem and math classes and i would say justscorea is the reason i scored A for both chem and math at a levels. Their teaching style is truly very unique and they don't merely reteach content like other tuition centres i've tried. The tutors Jay Jae and Jay also have extensive knowledge on how to score in the a levels!

I am from ACJC and i joined JayJae's H2 Chemistry class in 2024 with my grades at U. Now on my latest test i was only one mark away from B. I jumped 4 grades and JayJae really helped me understand topics properly with the perfect teaching content to doing practice ratio, unlike in school where they rush topics. His notes are very concise yet sufficient, 10/10 would recommend JSA’s tuition 😁😁

I am a current student of Just score A. I am a j1 student from JPJC taking the H2 chem classes with JSA. I personally really enjoy the fact that I can watch the recorded lessons at my own pace. I really love the notes that are given as they are concise and do not have unnecessary information like my school notes. This allows me to know what I need to revise and focus on before my tests.

I am a J1 student from ASRJC I have attended the H2 Chemistry classes at JSA. I was taught by Mr Jay Jae! Overall the tuition experience was actually really enriching because unlike my tutorials and lectures where I struggled to get full credit for marks in the practice questions. In Mr Jay Jae's class I felt like I gained a clearer more indepth perspective in how to score full marks for questions
