Results
Twelve years of students who stayed
No advertising. Just word of mouth, and 1000+ Surat students who stayed for the full Diploma. In their words:
After two years under his supervision, I topped my entire batch in maths despite taking AA HL. I owe to Rajendra sir my admission to LSE; he is the most significant person in my academic life.
It was at Rajendra sir's disposal that I started learning, and falling in love with, mathematics. He has helped me through IGCSE, IB, SAT, AP and ACT. A teacher, a mentor, and even a friend.
Slowly, MindLab became a home away from home. Over the years he helped me with IGCSE, SAT, ACT, AP and IB, which shows how versatile his teaching is. A true educator and a great mentor.
