Like others have said, you need more total time and training events under your belt. I would suggest 135 once you get the time, that way you will get professional-level training events (similar to 121) at the time of hire and then periodically for recurrent.

I hate to have to say this but you only have two things going for you in this situation...

1. Your busts occurred very early in your career
2. You have not busted a professional/turbine training event (135/121/Flight safety).

With your history it's important that you keep it that way. It sucks to have that kind of additional pressure but it's imperative that you don't fail any more checkrides, most especially 135/121. I think in the long run you can overcome this if you are willing to accept a possible career sidetrack (ie 135 or 91 flying for a while). But if you include any more failures in your track record, I'm guessing you will have a real hard time.

Also be aware that if you "clean up your act" so to speak you will still have to address this at interviews. It will help if you have some sort of an explanation. By that I do not mean "excuse"...you will have to take responsibility for what happened. But rather if there is some extenuating circumstances which you can identify and then explain how has been corrected it will ease employer's minds about your trainability. Something like working two jobs plus going to school, family problems/sick family member, maybe even a psycho ex-girlfriend. If you can't identify any such circumstance, do some soul searching and find something you can change to improve your ability to pass checkrides. Something has to change here...if you can't tell people what it is and how you changed it, you will have a hard time getting hired by anybody.

Thanks for sharing your details, it helps others who may be in a similar boat.
