Future Tier 4 visa - Undergraduate, success probability

[cdfr13]

Hi,

I have currently been offered an unconditional offer of a place from a "Highly Trusted Sponsor" and I have accepted it, I am currently waiting for my CAS which should arrive in a week or so. I have made my NON EU deposit.

I have 7200 GBP plus the rest of my fees of the first year, the first year is 4300 GBP and the 3 following years are 13050 GBP each. The amount of 10 500 will be held in my personal account for the 28 days as I am not from a "low risk"country.

I wonder if they will request further information on how I will pay my entire course as a private sponsor friend of mine is paying for this. Shall I tell them in my first application and submit his bank statements or shall I wait for them to ask for them, as I am already fulfilling the 40 points they request.


I have the Cambridge Advanced Certificate to prove my level of English.
- I have previous immigraitonal history.

1.- 2004 - 1 Year Student visa
2.- 2005 - 1 year student visa
3.- 2006 - 2 years partners visa
4.- 2008 I left the country as my relationship finished

I went to live in Prague Czech Republic and I was travelling from Prague to London very often, to visit friends, to wait for visas issued in prague, and I was writing a book also where London plays a major role. I never over stayed as a tourist and now back in México I genuinely want to study my degree in the UK as I feel is a great investment and one of the best education I could have in my field as I will be studying Psychology and I think to apply it in various nationals programs when back in México to help people understand themselves among other personal pursues.

Note: I have never been denied entrance to any country, I have my previous passport with previous visas and I have never been refused a visa either.

Questions:

-Would this imigrational history would affect my application negatively?
-Would they ask to see more funds or where they are coming from if the rest of the years are more expensive?
-Would a covering letter be helpful with my application, stating why i want to study in the UK and that I intend to come back to México when I finish.
-What are the probabilities of success?
- Where can I find further info or talk to someone specialised in the field?

I would like to submit a complete application covering all little gaps that might arise.

If anyone can help me on this I would be very grateful .
