+# 1. Goal
+An exam office checks if a student may register for an exam. A registration
+program calls the check before it books the seat. The check reports each
+rejection as a class-based exception.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_EXAM_REQUEST exists in package $TMP. It is active.
+- The interface has the public type TY_REQUEST. The components are:
+  STUDENT_ID (STRING), ENROLLED (ABAP_BOOL), PREREQ_PASSED (ABAP_BOOL),
+  PREREQ_ID (STRING), ATTEMPTS (I), REG_DATE (D).
+- An exam has a maximum number of attempts and a registration deadline. The
+  caller reads both values from the exam master data.
+- A prerequisite is another exam. PREREQ_ID is the id of that exam.
+
+# 4. Contract
+Create these classes in package $TMP.
+
+{{P}}EXAM_CHECK
+- The class is public and final. It has a public constructor.
+- Constructor: IMPORTING iv_max_attempts TYPE i, iv_deadline TYPE d.
+- Method CHECK: IMPORTING is_request TYPE {{P}}IF_EXAM_REQUEST=>TY_REQUEST
+  RAISING {{P}}CX_NOT_ENROLLED, {{P}}CX_PREREQ_MISSING,
+  {{P}}CX_NO_ATTEMPT_LEFT, {{P}}CX_DEADLINE_PASSED.
+- Do not add other public methods.
+
+{{P}}CX_EXAM_ERROR
+- The class is public and abstract. It inherits from CX_STATIC_CHECK.
+- Public read-only attribute MV_STUDENT_ID TYPE string.
+- Public read-only attribute MV_TEXT TYPE string.
+
+{{P}}CX_NOT_ENROLLED
+- The class is public and final. It inherits from {{P}}CX_EXAM_ERROR.
+- MV_TEXT contains the text 'The student is not enrolled.'
+
+{{P}}CX_PREREQ_MISSING
+- The class is public and final. It inherits from {{P}}CX_EXAM_ERROR.
+- Public read-only attribute MV_PREREQ TYPE string.
+- MV_TEXT contains the text 'The prerequisite exam is not passed.'
+
+{{P}}CX_NO_ATTEMPT_LEFT
+- The class is public and final. It inherits from {{P}}CX_EXAM_ERROR.
+- Public read-only attribute MV_ATTEMPTS TYPE i.
+- MV_TEXT contains the text 'No attempt is left.'
+
+{{P}}CX_DEADLINE_PASSED
+- The class is public and final. It inherits from {{P}}CX_EXAM_ERROR.
+- Public read-only attribute MV_REG_DATE TYPE d.
+- MV_TEXT contains the text 'The registration deadline has passed.'
+
+# 5. Business rules
+The method CHECK applies the rules in this sequence. It raises the exception
+of the first rule that fails.
+1. If IS_REQUEST-ENROLLED is abap_false, raise {{P}}CX_NOT_ENROLLED.
+   MV_STUDENT_ID contains IS_REQUEST-STUDENT_ID.
+2. If IS_REQUEST-PREREQ_PASSED is abap_false, raise {{P}}CX_PREREQ_MISSING.
+   MV_STUDENT_ID contains IS_REQUEST-STUDENT_ID. MV_PREREQ contains
+   IS_REQUEST-PREREQ_ID.
+3. If IS_REQUEST-ATTEMPTS is greater than or equal to the maximum number of
+   attempts, raise {{P}}CX_NO_ATTEMPT_LEFT. MV_STUDENT_ID contains
+   IS_REQUEST-STUDENT_ID. MV_ATTEMPTS contains IS_REQUEST-ATTEMPTS.
+4. If IS_REQUEST-REG_DATE is later than the registration deadline, raise
+   {{P}}CX_DEADLINE_PASSED. MV_STUDENT_ID contains IS_REQUEST-STUDENT_ID.
+   MV_REG_DATE contains IS_REQUEST-REG_DATE.
+5. Else the registration is allowed. The method returns without an exception.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_EXAM_REQUEST.
+
+# 7. Acceptance
+- All classes are active and have no syntax error.
+- The hidden tests pass.
+- The code has no ATC finding of priority 1 or 2.
+- Write your own ABAP Unit tests for the class {{P}}EXAM_CHECK.
