IB DCIO Tech 2026 - Need some clarity
I'm appearing for the upcoming DCIO (Tech) exam (I don't know when) and, to be honest, I know very little about how this exam actually plays out.
Based on the syllabus and the available PYQ (Test Booklet 0008741 – GAT DCIO), it looks like the technical section is roughly 85 questions (CS + ECE) along with 15 Quantitative Reasoning questions.
For the CS portion, I'm following multiple resources (NPTEL, GFG articles, standard textbooks, etc.), so I'm fairly confident about covering that. My bigger concern is the ECE portion, which seems to account for 43–48 questions—too significant to ignore.
NPTEL has excellent lectures for almost every ECE topic, but the content is extensive. Since I also want to prepare CS thoroughly (to keep my preparation aligned with exams like **IBPS SO (IT Officer)-**29 Aug and SEBI Grade A IT), I'm not sure how deep I should go into ECE.
For those who've appeared for the exam:
- Which ECE topics deserve the highest priority?
- Are there any good, concise resources for theory + MCQ practice?
- Is there any book, notes, or question bank that closely matches the actual level of the exam?
- If you had to prepare the ECE part in a month or two, how would you approach it?
Any guidance or resource recommendations would be greatly appreciated. Thanks!
