Well, I guess you have to try harder this time round. Study hard if you don't want to be 'Left Behind'. Failure is like the 'Virus Of Life'. They should be put with a 'Danger- Keep Away' sign. And 'Before I Forget', just do your best and next time when you made it, "Everything Ends" with a happy ending or else "All Hope Is Gone"..
Hah. Even song titles can be made into a motivational one..
But whatever it is, don't stop trying. Maybe do some time management. I've been there before and it's definitely a shameful experience.. Especially with your friends and families.
And doing private O is not cheap also.. Make sure you make full use of it. I took 2 subjects before and it cost me almost 300 bucks. So I hope this will motivate you to do better..
All the best!
