Hello, everyone. I am Zheng Tien from Penang. You can call me Nicholas. I am 18 years old and I will take my Pre-U studies (A-level) this July. I expect I will have tonnes of Physics question to ask Physics experts here. (Actually, I have one question now.) And I just passed my practical driving test yesterday. I will get my driving license soon. I look forward to meeting all of you. Thank you. Best regards, Zheng Tien.
