1. Did you regret for going thru form 6??izzit really so tough like others said?

50-50... it's up to u whether u enjoy ur form 6 or feel that it's torture...

2. Can share some experiences on your study? izzit really a MUST to study everyday for few hours??

me ar?? i depend 100% on tuition ... and i pass all my subject... kinda regret never did any self-study... to aim better results.

3. What subjects should be taken in science stream?

bio, physic, chemistry, maths T, further maths, additional subjects...??

4. The most important thing,can I still apply for uni(such as Utar) if I din do well or sumore even worst failed in stpm??

i think getting a F in STPM is kinda hard unless u blank like 80% of the exam questions... ^__^ and yeah UTAR & KTAR mininum requirement is 2 principles ( 2 C ) so i guess it's a sure-in for these two pricate unis but it's all varies for different colleges.

anyway good luck in ur STPM! and MUET has just change their syllabus so if u are the first batch it should be ok as they would normally lower the bar down to prove the new syllabus works.
