ORIGINAL WRITTEN REHEARSAL
Dhaka University Model Test for Exam
Choose a subject or the available combined paper. The 30- and 90-minute timers are practice options, not a claim about the institution’s current format. These original questions are not past papers. Answers stay in this browser; no school grade, coin balance or enrolment changes.
Set 1 of 1 available paper set.
5 written questions: 3 can be checked against the answer key; 2 need a guardian or subject teacher to review. Choose the relevant subjects for your target programme separately.
The timer starts when you choose Start model test.
You can leave or finish early without losing game progress. If time expires, the draft is kept and review opens. A timer is a rehearsal aid and cannot prevent leaving the page or changing a device clock.
Work on paper and enter the requested answer. Explain reasoning in the longer response boxes. Keep your work if you want a teacher to review it.
For the fraction (x²−1)/(x−1), consider the original domain as well as any simplified expression. Fair-coin questions assume independent tosses.

3x²+2 gives the local rate of change of the function with respect to x.
Differentiate both terms and define rate.
The automatic result counts exact supported answer-key matches. Other valid wording, working, handwriting and compositions need human review. It is not an overall examination mark or an admission prediction.
