A quick search of armynet for 'LEOC' gives the pre-reqs:
In order that all students arrive on LEOC at a common standard there are some pre-course requirements.
MK1 & eDW: All Late Entry officers commissioning on LE TOS 2010 are required to complete both MK1 & eDW prior to attending LEOC, this includes those selected in 2009 for commissioning WEF Apr 10 whose date of commission was brought forward for operational reasons. All Late Entry officers who were selected prior to 2009 and therefore commissioned on the extant TOS prior to the implementation of LE TOS 2010 who wish to transfer onto LE TOS 2010 are exempt from having to complete MK1 prior to attending LEOC. Further details can be found in 2009DIN01-221. The electronic Defence Writing package (eDW). It can be accessed through the ArmyNET site by clicking on the Reference portal and scrolling to the foot of the page where, under the âMiscellaneousâ heading you will find links to both JSP 101 and the eDW package.
You will also find some further reading and tips below which you may find helpful for when you attend LEOC.
TA P&P 2010 1.1.14 b. (2) ...Officers must complete Late Entry Officers Course (LEOC(V)) within 2 years of commissioning at which point they will be promoted to substantive Capt with a seniority date of the day they commissioned. Failure to attend LEOC (V) will result in the officer reverting to Lt and having to complete Junior Officers Tactic and Awareness Course (JOTAC(V)) and Military Knowledge 1(V) (MK1(V)) before being eligible to promote to Capt.

Well, the instructions are quite pacific. The pre-requisites are:
1. Ruler writing at not less than 10 WPM.
2. The ability to get knife edge creases into a sta-prest George at ASDA suit.
3. The complete inability to select a shirt/tie combination that matches, although "comedy" cartoon ties do score highly.
4. Ownership of at least one pair of slip on shoes, preferably with square toe and/or buckles.
Never forgetting that when the HQ element hits the more complex elements of the 7Qs planning cycle, the ability to mumble something about G4 "administration" and stroll away to polish their boots a little more, and press their collar just that little bit flatter. After all, a smart uniform is vital!.
9. A collection of photographs of a younger, slimmer self as a Corporal with the Company in the drill hall at ENDEX from a BAOR Exercise standing in front of a vertiginous pile of beer, wine, spirit & cigarette cartons brought back in one of the 10 âGDâ Bedfords taken from each Coy location.
10. To be fair the ability to out-run, out-drink, out carry & out-shoot the majority of the young whippersnappers, even when they are exempt fitness tests or are eligible to be timed using a calendar.
