Got 780 , gutted was basically got 41/51 when I needed 43

I got 20% on Network Device Security and 33% on operations of IP networks. So atleast I know where my weaknesses are, trying to keep a positive outlook on it but I really should of passed considering I have been working as a junior network engineer for 5 months and will be in fourth year for computing networking atmy Uni in August having aced 3rd year. Also feeling guilty due to the fact my wok paid for it and got nothing back for it.
