I'm nervous

I'm very nervous when I think about the first day in new school after my vaccation. (Now is the time of summer holidays in Switzerland.) Do you know? Last April, I wrote the Gymi exam (It's like +2 exam in Kerala). I was so happy when I got the result. I passed the exam. Juhuuu............ After the vaccation I'm changing to a new school and the school will decide after three months whether I could stay or not. It depends on my marks. I must work harder than ever. Pleeeeeeeeaaaase........ help me god.
