选择是个很痛苦的过程，学业上固然面临选择，工作又何尝不是这样呢，这个过程一定要想明白，我个人认为还是遵从自己的喜好来，任何人的意见都不能代替自己的喜好，否则会很难过。

I think you should be more independent and , cherish your already much blessed life

似乎看不是很明白，但能懂大概意思，现在怎么样了？奇怪，怎么我一直订阅的没有见这篇文章，不要着急，人生路很长，不是说现在走的稍微差一点就会决定一生，相反，现在你还正年轻，这一切都是财富，巨大的财富，能从过去得到一些经验与总结是最重要的，以后会走的更加顺畅。看了祖的新博客了吗？关于新邻居的那篇，他不是说了吗，他以前进大学以前也有缺点，毛病，但是什么时候都不晚，只要你认识到了，并勇于改正，未来的路更美好！相信自己！加油啊！

sorry to hear that...it's very frustrating when you don't hit the good grades, especially when you're looking towards higher education...
i'm not sure which aspect are you considering from...if financially, probably you can compare tuition fees vs resit A level...because either way you still reach your goal, probably a couple of semester difference (time & money concern)...
my personal experience was, my SPM and Senior High Unified Exam wasn't brilliant, so i switched from Science stream to Commerce, and took Business Admin (which is general, get a wide picture of the other side, Commerce, which i didn't study in secondary, and can easily get a job in the future)
because in the end, i still wanna study languages, one way or another, as that is my interest and passion, which my family did not support me to study after i graduate secondary...
now my question to you will be: are you confident enough to finish your pharmacist course in full...because if you're still not so sure, this may be a good time for you to reconsider the option...if you are, then...for my own opinion, is to resit A-level, because you've studied it before, and you're more prepared the next time...but the decision is yours...
feel free to drop me a message...though i may not be 100% useful and accurate...but, good luck!
