Graduate Entrance Mathematics Linear Algebra and Probability Core Problems
A Chinese ZIP study pack for linear algebra and probability, covering vectors, matrices, rank, eigenvalues, random variables, distributions, sampling and tests.
Keep objects and conditions together
This pack combines linear algebra and probability core problems through a condition-first review method. For vectors and matrices, track dimensions, linear maps, rank, inverse conditions, eigenvalues and eigenvectors. For probability, track the sample space, random variable, distribution, independence, expectation and the event being evaluated.
Use transformation and distribution cards
A linear-algebra card should state the object, allowed operation, invariant and target. A probability card should state the experiment, event, distribution, parameter and requested statistic. These fields make it easier to distinguish a valid transformation from an operation that changes the problem.
Mix calculation with interpretation
After a calculation, explain what rank, eigenvalue, expectation, variance or test result means in the problem. Include sampling, estimation and hypothesis-test conditions where relevant, and check whether a conclusion is about a parameter, a random variable or one observed sample.

Graduate Entrance Mathematics linear algebra and probability guide
Build condition cards for algebraic objects and random experiments, then connect each computation to its mathematical interpretation.
Before you start
- Use a ZIP extractor, formula cards and a mixed-problem error log.
- Know vectors, matrices, determinants, rank, eigenvalues, random variables and basic distributions.
- Prepare separate fields for dimensions, conditions, method, result and interpretation.
Installation steps
- 01
Build linear-algebra cards
Record dimensions, object type, legal operations, rank or eigenvalue conditions and the target quantity for each problem family.
- 02
Build probability cards
Record sample space, event, random variable, distribution, independence and parameter before choosing a probability formula.
- 03
Add interpretation prompts
After every result, explain its meaning for the transformation, distribution, sample or parameter in the original problem.
Quick start
- 01
Diagnose the object
Check dimensions and assumptions, identify whether the task concerns a matrix operation, linear map, rank, eigenvalue or probability event.
- 02
Select and verify a method
Apply the matching method, preserve conditions through each step and verify dimensions, signs, normalization or boundary values.
- 03
Complete a mixed review
Alternate algebra and probability questions, then classify errors by object recognition, condition, calculation or interpretation.
Usage tips
- Write dimensions and independence assumptions before formulas.
- Distinguish a parameter from an observation and a random variable from one realized value.
- Re-solve one problem with a changed matrix, distribution parameter or event to test transfer.
Troubleshooting and uninstall
Why does a matrix calculation look correct but fail later?
Recheck dimensions, operation order, rank or invertibility assumptions and whether the requested object is a vector, matrix or scalar.
Why is a probability conclusion overstated?
Separate the event, random variable, parameter and observed sample, then restate the conclusion with the exact condition and scope.
Frequently asked questions
Which linear-algebra fields should be recorded first?
Record object type, dimensions, legal operations, rank or eigenvalue conditions and target quantity.
Which probability fields prevent formula confusion?
Record sample space, event, random variable, distribution, independence, parameter and requested statistic.
How should mixed practice be reviewed?
Alternate algebra and probability items, then classify mistakes as object recognition, condition, calculation or interpretation.
