    Self Study Online has helped me build my confidence in test taking. Its rigorous curriculum with no-nonsense approach to each subject keeps you on your toes. The best thing is, I never felt bored studying and taking tests on the SOS platform. I strongly recommend SOS to any student who wants to take charge of his education and wants to succeed in real life exams.

  • Joyce Huang - University of Vermont

    Before I embarked upon Self Online Study, I tried many different online study sites. Most of them were either too expensive, or they were too trivial. SOS was the only study platform that offered me with high quality study material and tests problems that even top rated companies fail to provide. Step by step, SOS helped me train myself to take tests like a pro. If you want to succeed in competitive exams, don’t look any further. I owe my success to SOS.

  • Ryan Crane - University of Michigan

    I was skeptic of online study sites and believed a live classroom is the only way to master a subject. Self Online Study changed my belief. SOS offered me the perfect learning environment and helped me develop my expertise in gradual steps, at a pace that I felt was right for me. SOS challenged my understanding with a variety of interesting problems and then explained the solutions in a lucid manner. Today, I have no hesitation in saying that Self Online Study is the best online learning site today.

  • Debjit Das - University of Illinois at Urbana

    I was looking for SAT preparation programs but with SOS I not only found SAT prep programs, it also helped me enhance my knowledge on the subject matter. Their subject-wise and chapter-wise tests helped me build on my strengths and in addition get rid of my weakness across subjects. SOS is the biggest reason because of which I feel so confident today. Kudos to SOS.

  • Tiffany Wu - University of Los Angles

    I was putting my hard work but was disappointed with the poor study material and non-systematic approach of the online study sites I enrolled with. Got to know about SOS from one of my friend and enrolled with them trusting my friend’s experience. Today with a high degree of satisfaction I can say that SOS is the best when it comes to online study. SOS’s exhaustive curriculum along with highly customizable test preparation has done wonders to develop my knowledge and confidence.
