When i took L1 in dec, i did first elan mock 3 weeks before exam and my score was only 45
as long as you know what your weaknesses are, you have a good chance of passing.
what i did then was mock, then find percentage score for each subjects (corpin, fra, etc) to gauge which one i was weak to read the schweser for that subjects i was weak and eleventh hour for those i was ok
then mock again,repeat the process. By mock 6 (elan/schweser/cfai) i took notes which LOS i got wrong. I ended up doing 8 mocks. Thanks to this strategy, i passed with 8 subjects top marks, while quant and pm in mid range.
Btw when i did elan mock 3 i had severe migraine that i threw up. Elan mocks were so difficult
good luck all
