OGE Informatics study plan
OGE Informatics · Give each week a clear focus.
8 weeks · About 7 hours per week
Programming and algorithm execution & Computer modeling and algorithmization
Trace the execution of a given algorithm written in a natural-language or pseudocode form and write down every intermediate variable value
Convert a verbal problem statement into a flowchart or pseudocode algorithm with correct branching and looping
Hand-execute short programs with loops and conditionals and predict the exact final output
Identify the three basic algorithmic structures (sequence, branch, loop) inside a longer algorithm
Your checkpoint
A handwritten solution set of 12 algorithm-tracing problems, each showing a step-by-step variable table and the final output, self-checked against the expected answers
Programming and algorithm execution & Computer modeling and algorithmization
Write short programs that read input, apply arithmetic and string operations, and print a formatted result
Implement loops to accumulate sums, counts, and maxima over a sequence of values
Debug deliberately broken programs by locating the logic error and stating the correction in one sentence
Compare two algorithms solving the same task and justify which uses fewer operations
Your checkpoint
A file of 8 working programs (with sample input and verified output) plus a short written note on each of 4 debugging fixes
Information coding, number systems, and measurement of information
Convert integers between binary, octal, decimal, and hexadecimal by hand, showing the division or positional-expansion steps
Add and multiply small binary numbers and verify each result in decimal
Compute the information size of a message given the alphabet size or per-symbol bit count
Convert between bits, bytes, kilobytes, and megabytes in both directions without a calculator
Your checkpoint
A one-page conversion reference sheet you wrote yourself plus 20 solved conversion and information-volume problems with work shown
Digital literacy and information technology fundamentals & Information coding, number systems, and measurement of information
Classify a set of real-world scenarios by the type of information process involved (storage, transmission, processing, coding)
Explain, in writing, the difference between data, information, and knowledge using your own examples
Solve mixed coding problems that combine number-base conversion with text or graphic volume estimation
Estimate the storage needed for a described text or image file and state all assumptions
Your checkpoint
A timed 45-minute mock quiz of 15 mixed domain-1 and domain-2 items scored and error-logged
Computer systems, software, and file organization & Information and communication networks, internet services
Describe the function of core hardware components and match each to a described symptom or use case
Interpret a full file path and identify the directory, file name, and extension, and classify the file by type
Explain how a client request reaches a web server and what a domain name and IP address each do
Distinguish LAN from WAN and identify which network service (email, web, file transfer, search) fits a given task
Your checkpoint
A concept map linking hardware, software, and network services, plus 15 solved matching and short-answer items
Practical ICT tasks (spreadsheets, text processing, search, databases) & Information security and safe use of ICT
Build a spreadsheet that uses formulas, relative and absolute references, and at least two functions to answer a stated question
Write and refine search queries using operators and judge which of several results best matches an information need
Apply text-processing operations: find and replace, formatting, and extracting a summary from a document
Identify three concrete unsafe-ICT scenarios and state the specific protective action for each
Your checkpoint
One finished spreadsheet workbook with source data, formulas, and a short answer cell, plus a written security checklist of 8 rules
Practical ICT tasks (spreadsheets, text processing, search, databases) & Digital literacy and information technology fundamentals
Design a small relational table structure and write queries or filters that return a specified subset of records
Complete a full practical spreadsheet task under time pressure using only allowed functions
Explain what a database record and field are and predict the result of a described sort and filter
Apply digital-literacy judgment to evaluate the reliability of two conflicting online sources
Your checkpoint
A completed timed practical task (spreadsheet plus database filter) done in 40 minutes and self-graded against a rubric you wrote
Programming and algorithm execution & Information coding, number systems, and measurement of information & Information security and safe use of ICT
Re-solve every item you previously got wrong and confirm each fix without looking at the old answer
Complete two full-length timed mock exams and record the score for each domain
State the two highest-error domains and list the specific skills to review in the final days
Recite the key formulas for information volume and number-base conversion from memory
Your checkpoint
A final error log with every previously missed item re-solved, plus two scored mock-exam results and a one-page last-week review list
Milestones
Week 2: You can hand-trace any short loop or conditional program and predict its output correctly on 10 of 12 attempts
Week 4: You score at least 70% on the timed mixed domain-1/domain-2 quiz and can do base conversions without a calculator
Week 6: You produce a working spreadsheet with correct absolute references and pass your own 8-rule security checklist
Week 8: Both full mock exams are completed under time with every wrong answer re-solved and logged
