Is this course right for 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.
What Java covers
The course follows the full syllabus, 9 units.

Students from around Dehradun
A student anywhere in Dehradun can take Java 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.
How Dehradun students attend
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, exactly as they would in a classroom. 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!

I have joined kwick revision course before board examination. It found very useful for preparation of board examination. Educator cover all the topics. Investment of time was worth. Study material and sample paper practice were well organised.
