IB JIO Grade-II Technical study plan

Map the syllabus of Computer Fundamentals and Electronics into a one-page checklist of subtopics, then rank each subtopic by your current confidence on a 1-5 scale

Define and contrast the core hardware vocabulary (CPU, ALU, registers, cache, RAM vs ROM, bus types, motherboard, storage interfaces) in writing without consulting notes

Convert between number systems (binary, octal, decimal, hexadecimal) and perform two's complement arithmetic on at least 20 practice items

Draw and label the OSI and TCP/IP layer models from memory and state the protocol and device operating at each layer

Build a personal glossary of at least 40 networking terms with one-line original definitions

Explain the difference between circuit switching and packet switching and describe how a packet travels from a browser to a web server, hop by hop

Calculate subnet parameters (network address, broadcast address, usable host range, number of subnets) for at least 15 CIDR problems

Classify the main modulation techniques (AM, FM, ASK, FSK, PSK, QAM) and state one practical application of each

Compute bandwidth, bit rate, and channel capacity using the Nyquist and Shannon formulas on 10 numerical problems

Summarize five common cyber threats (phishing, ransomware, man-in-the-middle, SQL injection, DDoS) and one concrete defence against each

Solve at least 30 mechanics problems covering Newton's laws, friction, work-energy, momentum conservation, and circular motion

Derive and apply the equations of uniformly accelerated motion and projectile motion to 10 problems

Practice 25 algebra problems on quadratics, progressions, logarithms, and permutations and combinations

Build a formula sheet for mechanics and algebra limited to one page in your own words

Record every wrong answer in an error log with the reason for the mistake (concept gap, calculation slip, misread question)

Solve 25 electricity and magnetism problems on Ohm's law, series and parallel networks, Kirchhoff's laws, capacitors, and magnetic force on a conductor

Solve 15 optics problems on reflection, refraction, lenses, mirrors, and the lens formula, including sign conventions

Apply differentiation and integration to 20 problems on rates of change, maxima and minima, and definite integrals

Compute mean, median, mode, standard deviation, and variance for at least 8 data sets by hand

Re-derive from memory the three most frequently missed formulas identified in your error log

Solve 20 modern physics problems on photoelectric effect, atomic models, nuclear decay, and mass-energy equivalence

Solve 20 trigonometry problems including identities, heights and distances, and inverse functions

Solve 15 calculus problems on limits, continuity, and curve sketching

Explain in writing how a p-n junction diode, a transistor in common-emitter configuration, and a rectifier circuit behave

Review the full error log and rewrite corrected solutions for every entry

Solve 40 numerical ability problems on percentages, ratio and proportion, averages, profit and loss, and simple and compound interest

Solve 30 reasoning problems on series completion, coding-decoding, blood relations, direction sense, and syllogisms

Practice 10 seating-arrangement and 10 data-interpretation sets under a five-minute-per-set limit

Identify and write down three shortcut techniques for each of the two weakest reasoning question types

Time yourself on a 30-question mixed set and record the time spent per question type

Complete 20 reading-comprehension passages and justify each answer by quoting the exact supporting line

Correct 50 grammar and usage items covering subject-verb agreement, tense, articles, prepositions, and active-passive voice

Write 10 short paraphrases and 10 one-line summaries to practise precision and economy of language

Review six months of current affairs in science, technology, defence, and space, and note 30 key facts with dates

Revise the constitutional bodies, national institutions, and basic economic terminology most often tested in general awareness

Take two full-length mock tests under exam timing and mark every uncertain answer for later review

Re-solve every question missed in both mocks and classify each error by domain and cause

Revisit the weakest two domains identified by mock scores and solve 20 targeted questions in each

Recite from memory the one-page formula sheets and the 40-term glossary, checking for gaps

Finalize a one-page exam-day strategy covering question order, time allocation per section, and when to skip
