I am going to die under the hands of Science

Oh gosh...i am so going to fail physics! Currently on the chapter of pressure and i am indeed under a lot of pressure as i study this chapter. Maybe it is me who has low understanding but somehow, i just don't understand what my trainee teacher is teaching. She seems to be confusing me or maybe i am just confused and dumb. But i don't know where i don't understand. This just sounds bad. Even if i have queries, i also don't know how to ask. Haiz...in this case, how can i not fail physics? Well, in this case, i shall depend on my chemistry but it is nothing better. When i just got to know oxidation and reduction, i am very confused and all the formulas and words are flying around and i really don't know how to work on it. I think it is either mr ong or jolyn who said that after many practicing, you will understand oxidation and reduction. Initially, i do not believe it because all i know is that I AM CONFUSED! But after practices on my workbook and worksheets, i manage to get the hang of it. It seems like chemistry is all on practicing. I knew it during secondary 2 but because i am so lazy, i did not want to apply it on secondary 3 but i am wrong. I have to apply it no matter what. Physics may be about practices but i don't really feel like practicing on physics but i will just read through the textbook until i understand which works somehow. Nowadays, i really dislike physics lesson. It seems to be very fast but just cannot slow down but my trainee teacher says that we are slow... Omg...if she gets too fast, my heart will skip a beat and i will not be able to catch up and definitely, i will fail my physics. Haiz...maybe taking physics is a wrong choice but it is kind of too late to say anything now. I really hope miss ng can come back and teach us physics. At least, i can absorb what she says into my brain and at least i will not fail my physics. But i have tolerate until term 4. Physics can be so confusing that i really want to give up. Physics shouldn't be that difficult right? But why all of the sudden, it just seems so extremely difficult that i will die under the hands of physics? Or maybe it is just the chapter pressure that is so pressurizing? All i like about physics is the practical. Ok fine, i like all practicals no matter physics or chemistry. I just get the hang of practical so much faster than theory. And, tomorrow there is practical for physics! WOOT!!! No need to listen to confusing theories!!! But that is just for one day... Haiz... Textbook seems to be more useful than notes but notes just have more work examples. Oh gosh...how am i going to survive under the hands of Science?!?!?! So stressful and later got migraine -.-
