Can you plz write me an email!Hello Serha,
Really sorry for the undesirable outcome to your application especially after the long wait. One would think a delay in decision for that long was going to swing the outcome in your favour...Normally, I will recommend you apply for your GCMS note so you have a full understanding on what led to the refusal. But if the reasons you listed were all stated in your refusal, then I think you have your pointers already.
What you would need is to address the concerns raised in your refusal before submitting another application. I'll advise you not to allow yourself to be tempted into rushing to submitting another application until you have carefully addressed the reasons. Reach out to your Uni, defer your admission till the next convenient time.
As regards travel history, I wouldn't know the countries you've been except you'll like to share but it can make or mar your application. For me, I did my Masters in the UK so I guess it prolly helped. I believe you have a chance for success with your next application.
