BHSEC (Class XII) study plan

BHSEC (Class XII) · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Mathematics & English

Re-derive the core Class XII calculus results (limits, derivatives, definite integrals) from first principles in a formula notebook
Solve 40 mixed mathematics problems across calculus and algebra, logging every error and its cause
Draft 25 English comprehension answers under a 12-minute-per-passage limit
Build a personal error log template and start populating it for both domains

A dated formula notebook plus an error log containing at least 40 mathematics and 25 English entries, with each error tagged by cause

Week 2

Work through 50 mathematics problems on vectors, three-dimensional geometry and probability, timing each set
Derive and memorize the ten most-used physics formulae for mechanics and motion, then apply each to two numericals
Solve 30 physics numericals on kinematics, laws of motion and work-energy, showing full working
Review last week's error log and re-solve every missed mathematics item cold

A timed problem set of 50 mathematics and 30 physics questions with a scored answer sheet showing at least 80 percent accuracy on re-attempted items

Week 3

Write eight Dzongkha essays of 250-300 words on current-affairs and cultural themes, each within 35 minutes
Memorize and correctly apply 60 Dzongkha spelling and grammar rules in written sentences
Complete three full English writing tasks (letter, report, essay) and self-assess against a marking checklist
Read two Dzongkha prose passages and summarize each in five sentences

A portfolio of eight corrected Dzongkha essays and three English writing tasks, each annotated with the specific rules or criteria applied

Week 4

Balance and solve 25 chemical equations, classifying each reaction type
Solve 30 numericals on mole concept, stoichiometry and solution concentration
Draw and label 15 biology diagrams from memory (human systems, cell structure, genetics crosses)
Explain in writing the ten highest-yield biology processes, capping each at 60 words

A mid-plan mock test of 40 questions split evenly between chemistry and biology, scored and reviewed with a written remediation list

Week 5

Solve 35 physics numericals on electricity, magnetism and optics, drawing a circuit or ray diagram for each
State and apply the key chemistry definitions and trends across periodic properties and bonding
Complete 20 chemistry reasoning questions requiring justification rather than recall
Re-test every physics and chemistry item missed in weeks 2 and 4

A two-hour timed combined physics and chemistry paper scored above 70 percent, with a corrected version of every wrong answer

Week 6

Work 30 economics numericals on elasticity, cost curves and national income aggregates
Draw and interpret 12 economics diagrams, writing a two-line explanation for each shift
Prepare 20 journal entries and post them to ledger accounts, then extract a trial balance
Solve 15 accountancy problems on depreciation and final accounts of a sole trader

A complete accounting cycle exercise (journal to trial balance) plus a scored economics numerical set, both checked against model solutions

Week 7

Outline the twelve core business studies concepts and attach one Bhutanese or regional example to each
Answer 20 case-based business studies questions in exam format and length
Write and debug 12 short programs covering loops, functions, arrays and file handling
Trace 15 code snippets by hand and record the predicted output before running them

A working code file of 12 programs with commented output, plus 20 graded business studies case answers

Week 8

Sit two full-length timed mock papers under exam conditions and score them strictly
Re-solve every item still flagged in the error log until each is correct twice in a row
Recite and write from memory the key formulae and grammar rules across all ten domains
Finalize a one-page per-domain revision sheet for last-day review

Two completed mock papers with scores, a fully cleared error log, and a ten-page condensed revision pack

Week 2: Mathematics and physics error logs show at least 80 percent of missed items re-solved correctly on a cold retry

Week 4: Combined chemistry and biology mock score reaches at least 65 percent, with a written remediation list per weak subtopic

Week 6: Economics and accountancy deliverables are complete and at least 70 percent accurate against model solutions

Week 8: Both full mock papers scored at or above 70 percent overall, with no domain below 60 percent and the error log fully cleared
