Minor fixes
- 🐛 Fixed issue where the start time of the exam display wrongly. #92
- I arrived early at the exam venue because I thought the exam starts at 2pm 😂. No wonder no people come yet at that time. Aiyaa final year final semester student already... 🤦♂️
- 🐛 The exam now will mark as finished only after the exam ends (+3 hrs from the start time). #93
