  1. RCT = Students randomly assigned;
  2. Non-RCT = Students who were free to choose between small group tutorials and interactive seminars;
  3. Questionnaire A = Questionnaire sent to all students three weeks before the start of the block;
  4. Study hours = hours/week spent on didactic lectures, small group tutorials and individual study;
  5. Grades on a ten-point scale: 0 = lowest; 10 = highest;
  6. * RCT: SG vs IS: P = 0.091; Non-RCT: SG vs IS: P = 0.086 both by chi-square test;
  7. **all RCT vs all Non-RCT: P = 0.966 by chi-square test;
  8. *** P value is a result of Student Unpaired t test and represents non-RCT participants: SG vs IS.
