CBSE Class 11 Computer Science (CS) Classes in Dehradun, Online Coaching

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 11 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.

Before joining Kwickprep, I honestly struggled a lot with Computer Science. I couldn't understand most of the concepts, but thanks to Kajal Ma'am, that completely changed. Her teaching helped me improve so much, and I'm really grateful for that. She's one of the best teachers I've ever had. She explains everything with so much clarity and patience, and even if I didn't understand something the first time, she would happily explain it again, as many times as needed. Yes, sometimes she got strict, but I know it was always for our own good. What I appreciated most was the way she helped us solve a variety of question papers during the Kwick Revision sessions. That really boosted my confidence. The course overall was great, the materials, the teaching, and the support. I'm quite satisfied with everything. Thank you, Kajal Ma'am and Kwickprep, for helping me grow in a subject I once found impossible!
