Why this fits a Dehradun student

Most Dehradun schools follow the Uttarakhand Board (UBSE), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the UBSE computer paper itself, so this course suits a Dehradun student in one of those schools.

✓Live classes at Indian Standard Time, never pre-recorded
✓Small batch or one-to-one, so a Dehradun student can interrupt and ask
✓Taught by Kajal Ma'am, teaching computer subjects since 2006
✓Free demo class before any payment

Students across Dehradun

A student anywhere in Dehradun can take CBSE Class 12 Computer Science (CS) with us — Academy, Clement, Dalanwala or Doon included — because the class is online and there is no centre to travel to. Dehradun sits in Uttarakhand, where the Uttarakhand Board (UBSE) runs alongside the national boards, so we are asked about both.

Every class is live at Indian Standard Time, in a small batch or one-to-one. Nothing is pre-recorded, so a student in Dehradun asks questions in the moment. Recordings are provided for revision only.

I was also preparing for my JEE entrance exam. I thought that I was not able to complete the syllabus in a short period of time, but as per the commitment, the course has been completed, and I got a thorough revision too, which was quite useful. The Kwickprep course, study material, and quality of teaching were good. I got support during my practical examination. Doubt solving took place in very less time. I am satisfied with the course.
