Formerly known as Sandy Institute, Sandy Leksana Institute (SLI) is specialised in preparing candidates for international standardised tests, such as GMAT, GRE, SAT, IELTS and some other tests.
SLI (first under the name Sandy Institute) was established on the 4th of August 2009. Our courses were initially carried out at the founder’s residence in Menteng area, Central Jakarta, but because of the growing number of students, we moved to Gedung Sentral Cikini, Jalan Cikini Raya, Jakarta Pusat in September 2012.
Our strength lies in
- our highly qualified teachers
- the wide-ranged materials covered (from basic to advance) with detailed explanation
- the teacher’s availability to discuss materials / tasks with students every day
- the primary language of instruction, i.e. Bahasa Indonesia for GMAT/GRE classes.
- free unlimited simulation tests offered for our students

Waktu sekolah, kita menggunakan matematika untuk solving problems. Sementara di GMAT, kita pakai matematika untuk mengasah logika. Di GMAT, kita juga diminta untuk membaca secara kritis, bukan sekedar menerima informasi yang ada dalam bacaan. Ini membuat GMAT prep sendiri menjadi berat. Di sini lah peran Sandy Institute. Sandy Institute jago banget dalam melatih logika matematika kita dan daya kritisi kita dalam membaca. Sistem pengajarannya juga relatif relax, jadi kita juga tidak stress sewaktu belajar di kelas. Terima kasih Sandy Institute.

Before deciding to enroll to one of the program in Sandy Leksana Institute, I heard about it from some of my friends who had been successful in reaching their intended score in IELTS test.
After giving it some thoughts, I finally decided to take the 20 hour session. I’ve taken IELTS test once, and one of my weakest points was writing and decided I needed structured exercises that would improve my writing skill and at the same time improve my theoretical knowledge about the language.
From day one, Sandy Leksana Institute gave me exactly what I needed plus an atmosphere in which I was challenged enough yet still able to enjoy the lessons.
After several weeks of hard work, everything is finally paid off. I got overall band score of 8, 8.5 in Listening, 8.5 in Reading, 7 in Writing and 8 in Speaking.
Thanks Sandy and SLI, you’ve given me one of the most rewarding learning experiences ever.

I was in a moment where I want to get myself accepted to the masters degree programme at a university in the UK. One of the compulsory requirements was to hit an overall good score in the IELTS test, hence I was looking for a course who could help me to achieve such. One of my friends told me about Sandy Leksana Institute and I googled it afterwards. I immediately enrolled myself for the IELTS preparation class and the rest of the story was all fantastic.
A bunch of thanks to Sandy Leksana Institute for giving me a chance to hone my IELTS skills. I was able to get high marks, i.e. with the overall 7, since SLI equipped me with a variety of IELTS simulations, which in turn made me very confident in dealing with the real test

Awalnya saya beli buku GMAT tapi bingung mulainya belajar darimana. Setelah browsing di internet untuk cari info dimana saja tempat les GMAT, SLI salah satu tempat les GMAT yg reviewnya bagus. Berhubung sambil kerja, jadi saya hanya bisa les pada malam hari atau weekend, dan SLI ada kelas private untuk malam dan weekend buat group.
Setelah daftar dan masuk kelas gorup GMAT, ternyata cara mengajarnya oke dan sistematis, materinya juga lengkap. Pengajarnya, mas Sandy, pintar banget dan sabar juga ngejelasin berkali-kali kalau kita ga ngerti. SLI juga provide modul latihan yg bisa kita kerjain diluar jam les, dan bisa cek jawabannya juga via WA ke pengajarnya. Materi SLI lengkap dan komprehensif buat basic kita ambil tes, tapi kita harus tetep rajin latihan sendiri juga.
Overall, SLI recommended buat GMAT preparation. Sukses terus ya! Thank you!

First time I heard about Sandy Leksana Institiute is when they conducted a simulation of the SAT Test at my school, SMU Kanisius. I had always wanted to take the test but I kept procrastinating. When I got the results of the simulation, I scored a low score of 1470. Therefore, I sought out help from Sandy Leksana Institute. After about 40 hours of private class, I could finally understand the ins and the outs of the SAT. It got to the point where I was very comfortable with tackling questions that had seemed at first alien to me.
After the rigorous lessons and so many simulation tests, I took the real SAT and this time was much more well prepared. When the resluts came out, it turned out that I increased my score by a high margin. This is all thanks to the tremendous mentoring by SLI.
Thank you Sandy Leksana Institute

‘When I first read through the SAT preparatory book alone, I panicked. There were so many things I didn’t understand, and I could barely guess at the answers of half the questions. After attempting to study alone, and only becoming more and more frustrated, I enrolled in Sandy Leksana Institute- a mere 2 months before taking the SAT exam. During my diagnostic test, I failed the maths section of the SAT, and achieved a barely passing score in the 1500’s. After just 12 meetings (1 month) of extensive training, explanations, and practices set for me, I finally understood exactly what I needed to do for the exam. It was so much easier when I listened to the teacher’s to-the-point explanations!
2 months later, when I checked my SAT scores, I couldn’t believe it. I had increased my score to 2340/2400, scoring full marks in the Reading section, and achieving 780/800 for Maths. Thank you to Sandy Leksana Institute and the extremely effective coaching that has helped me achieve this!’

When I was so desperate in looking a place to improve my English, a friend of mine told me about Sandy Leksana Institute where she attended the course successfully.
When I did my placement test for the first time at Sandy Leksana Institute, I did not feel confident at all and I got a really bad score. Therefore, I decided to take private courses for more than a month. One thing that I benefited from Sandy Institute was not only the theories and practices but also the encouragement and the motivation which really help me to make a significant improvement in this IELTS test.
My weakness in IELTS test was reading and writing section, SLI gave me really simple explanation and also very useful tips how to boost my score on those both sections. Only in 2 months I made a very good improvement, it started at overall 4 then increased to 5.5 overall and finished at 6.5
Thank you SLI !!!

“I worked with Sandy mostly on the Verbal Section of the GMAT exam. He is a great teacher, especially solid in English. You can have a question for him at any time of the day and he is always available. You can feel his experience in teaching, which makes the class run smoothly and effectively. I recommend Sandy-institute for anyone in Jakarta who is willing to improve his score on the GMAT exam.”

Every Monday-Wednesday-Friday I have to come to Cikini at 6-8am in the morning to do the simulation test on GRE and learn about it before I go to work. Then, in the Saturday, I have to attend the 6-7 hours group course on GMAT and on Sunday, I take the GMAT simulation test for 3 hours. I almost have no life at that months. Well, in fact Mr. Sandy even advice me in the 1st class: “Dini, from now until you finally take the real GMAT test, your priority is GMAT. Your Saturday is for GMAT. Family, boyfriend, friend, office, and other.. its your next priority after GMAT if you want to be successful with GMAT.”
Now you can imagine how hard and challenging is learning GMAT and how to improve the score. I really appreciate how Mr. Sandy really want the students success and he is very committed with all the students. Respect!

Sangat berkesan!! Sandy Institute membantu saya untuk mewujudkan mimpi saya. Disini saya bertemu mentor yang sangat care dan saya berkenalan dengan teman teman dengan mimpi yang sama. Cara pengajarannya pun juga dari dasar dan detail. Setiap hari kita bisa berkomunikasi dan dibantu dengan mas Sandy melalui WA, dan ini sangat membantu kemajuan yang saya alami.
