o well... had 3 tests today...history gt postponed 2 wks later
tmr gt amath re-test...
i m currently living in the world of tests.....

phew..i managed to survive my 3 tests today...but i found out i had a few careless mistakes in physics tests...
1st: i didn't no/forgotton how to find average velocity...its quite stupid of me, when the ans is somehow in front of me-.-
2nd: i dunno wat is retardation, i guess it's deceleration...
3rd: i dunno wat does the ratchet do on the micrometer screw gauge...i guess is to reduce the pressure acting on the measured object...
4th: i didn't read the qn properly...i just saw a 'nano' word, and i wrote the ans 10 to the power of -9, which i think the ans is wrong-.-

bio test came from the 10-years series book.....some questions were repeat-.- quite fustrating to write answers over & over again....plus i didn't really read on the specialised cells...so i dunno how to ans xylem & root hair cell.....

sup~
