Comprensión Lectora (65 Q)
Target ~138 sec/question. If a question takes more than 207 seconds, mark for review and move on.
Competencia Matemática 1 (65 Q)
Target ~129 sec/question. If a question takes more than 194 seconds, mark for review and move on.
Competencia Matemática 2 (55 Q)
Target ~153 sec/question. If a question takes more than 230 seconds, mark for review and move on.
