• Algorithms & Dynamic Programming
  12 questions · 30 minutes · ~150 sec/question
• Graphs & Traversal
  12 questions · 30 minutes · ~150 sec/question
• Arrays & Strings
  10 questions · 25 minutes · ~150 sec/question

Google OA scoring & marking scheme

Strategy: Google OA has no negative marking. Attempt every question — blank answers cost you potential marks but cannot pull your score down.

Scale: Google OA (out of 34).

How Google OA is conducted

• Mode
  Standard — practice without proctoring on Wrexa Edge, or enable optional webcam proctoring to simulate test-day conditions.
• Test format
  Linear / fixed-form — every candidate sees the same number of questions per section.
• Backtracking
  Allowed — you can revisit and change answers within a section.
• Mark for review
  Available — flag tough questions and return to them before submitting the section.

Google OA time strategy

With 34 questions in 85 minutes, you have about 150 seconds per question on average. Successful candidates aim for the following pacing on each section:

• Algorithms & Dynamic Programming
  Target ~150 sec/question. If a question takes more than 225 seconds, mark for review and move on.
• Graphs & Traversal
  Target ~150 sec/question. If a question takes more than 225 seconds, mark for review and move on.
• Arrays & Strings
  Target ~150 sec/question. If a question takes more than 225 seconds, mark for review and move on.

Wrexa Edge's analytics show your actual time-per-question after every mock so you can spot which sections you're losing time on.
