Reading Comprehension Last month, my roommate and I decided to revamp our study habits for the upcoming final exams. We realized that simply memorizing definitions was not enough; we needed to adapt our strategies to fit the specific requirements of each course. Initially, we adopted a rigid schedule that required us to study for four consecutive hours every night. However, after a week, we found that our concentration levels dropped significantly. To address this issue, we decided to take on a different approach: breaking down the material into smaller, manageable chunks and taking regular breaks. This method allowed us to absorb the information more effectively without feeling overwhelmed. Additionally, we took the opportunity to clarify any confusing concepts by consulting with our professors during office hours. By the end of the month, not only had our grades improved, but we also felt less stressed about the exams. The key takeaway for us was that flexibility and consistent effort were far more important than rigid adherence to a single plan. According to the passage, what was the primary reason the students changed their initial study schedule?
