What Students Say

Trusted by students globally for achieving top grades.

“This is an appreciation message for you, sir! Left today's last class with a sad heart 😭. Thank you so much for the best chemistry classes but bunch of valuable lessons too! Really appreciate you for being the greatest supporter and mentor. Hope you continue to make me work harder in the future as well. Finally the best my concepts were unclear but your way of teaching simplified everything!”

“Assalamoalaikum Sir, hope ur doin well..! What a journey can't express my feelings, I hated Chemistry since year 7 😭 and I am so grateful that I joined or batch and became ur student. I hated it but now I love Chemistry, I hated it.. But when I joined ur batch it became a love-hate relationship. I would never imagine in a million years that I would be scoring an A* in my Chemistry. Its all because of you, the way you teach, the way you clarify concepts, the way u put fun in the reactivity table. I will never forget the guidance of you, we will never forget our time together but we have to move forward in our lives. Just like atoms are bonded by second. Kisi kun with whom bonding hai wohi pata chaley ga... Jiss ke liyay aapki baat itni badi hai itni kin ki nahi hai. Don't forget that we have been your student and if there would be 190 students I would be one of them. Thank you so much Sir. You are one of the best. Aur koi bhi bacha iska matlab in no other words!”

“Truly, my words can't express how grateful I am to be your student Sir. May you have a long successful life ahead of you, and may you be very well recognised in the eyes of people. It's truly a blessing to be a part of the SOS family, I had chemistry classes with you for 6 months not just about chemistry.. but life lessons too. You truly are a fatherly figure and teacher like you! If we get lucky enough it is because of your hard work and dedication, and I'm so glad I attended the class with you. You've taught me a lot with such a strong grip on chemistry. I will cherish every moment in the class and immediately after the class.”

“Assalamoalaikum sir, i hope ur doing well. Tbh the way you teach, the hard work and dedication you put, is worth 3 years. It was never a teacher student bond rather a brother-brother bond we had. You are no younger brother sir.”
