Guaranteed Success or
Full Refund

11+ Entrance exams are among the most rigorous and challenging tests for students. In London, for example, only 1 to 3 out of 100 students qualify in the 11+ entrance exams. Still, Chowdhury’s Tuition Centre guarantees that every 11+ candidate will qualify for at least one of the grammar schools, or we will refund your money. Since 2012, we have been running this Guaranteed Scheme for a limited number of students. From August 2026, we guarantee that every child will be successful, or we will refund the fees paid to us. We also guarantee success for all GCSE maths students or money back. Both schemes will be implemented by legally enforceable contracts, and there is no hidden term. Please see below for more information.

11+ Candidates

Chowdhury’s Tuition Centre is so confident in its methods and track records that we guarantee your child's success in the entrance examinations. We accept students whom we deem to have the cognitive ability and the work ethics to be successful If we fail to deliver, we will refund full tuition fees. From August 2026, all new 11+ candidates will be guaranteed qualification. For perspective, to gain admission to top super-selective schools like QE Boys or Henrietta Barnett, a candidate’s minimum raw score must be between 85% and 95% to qualify before age standardisation. The key factors behind our success are top quality teachers, small groups, customised study plans and pastoral care.

Please find below the terms and conditions for this guaranteed place.

  • Your child/ren must sit for the 11+ entrance exams to a minimum of 3 different grammar schools.
  • Your child must attend our course for a minimum of 9 months. Late starters must attend additional top-up lessons to catch up with the rest of the group.
  • Parents must ensure their child completed the homework properly and maintain a minimum of 90% attendance.
  • Your child must maintain an average of 70% in the vocabulary exams.
  • Failure to observe any one of the above conditions will invalidate this guaranteed place arrangement.

GCSE Maths Candidates

All GCSE candidates are guaranteed to achieve at least one level above their schools’ expected grades in maths. If they fail to attain it, we will refund the full amount paid as a tuition fee in Year 11. In other words, if a school’s predicted grade is 8 for a student, we will ensure s/he receives 9, or if a student’s predicted grade is 6, we guarantee that s/he will get a minimum of 7. If a student’s predicted grade is 9, and s/he fails to achieve it, we will also make a full refund.

The terms and conditions for it are given below:

  • A student must receive a minimum of 7 months’ tuition at Chowdhury’s Tuition Centre.
  • We will organise additional and extended practice sessions during the final 3 months before exams, and a student must attend these sessions.
  • A student must complete his/her homework properly. Failure to complete it may result in the termination of a student's guaranteed placement.
