University: it must be done based on the distribution of class hours and practices and the number of credits for each subject.
One option is to dedicate each day of the week to a subject, making a review of the work done during the last seven days in an exhaustive manner. In this way, you can take all the subjects up to date.
Bachiller / VET Superior Degrees: from the class schedule, it is convenient to spend 10/15 minutes every day to review what has been done during each class, reading the subject explained by the teacher, reviewing the exercises worked… Next, do the work or exercises.
In addition to the daily work, it is convenient to dedicate time to make a weekly review of the contents that have been worked during the week and that will serve us for the preparation of the exams, and the preparation of works, projects, etc.
All: the study schedule for exams must be established, always starting from the date of completion (or delivery of the work) and realistically assessing the time needed to prepare them well.
