Values and decisions

15-minute session: read for 3 minutes, trace for 3, experiment for 7, and complete the check for 2. Spend longer whenever you need.

A decision chooses which statements run. The policy here is “ready at 80 or higher.” Trace 85, 79, 80, and 81 before running each case. The comparison includes 80. A program that prints the right answer for 85 may still be wrong at the boundary. Add a separate check rejecting scores below 0 or above 100; rejection and needing practice mean different things.

Object Pascal classes and Objective-Pascal are distinct. First learn class, construction, and Free using the Linux lab. Objective-Pascal adds Objective-C interoperability through mode switches; this lab does not provide that Apple runtime.

program AgilaStudy;
{$mode objfpc}{$H+}{$assertions on}

var Score: Integer;
begin
  Score := 85;
  if Score >= 80 then writeln('Ready') else writeln('Practice');
end.

Expected result: Ready

Practice and evidence

Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.
