Hi there, I went through the BT, level 1, study notes this week end and I feel ok with most parts of the course... But I would need something more exhaustive for the Quant section. Firstly, I would like to know if the BT videos go deeper into the explanations?! Secondly, I don't want to buy the $250 core reading from GARP since I only need one book... So is there a cheaper alternative to deepen the quantitative analysis section? Many thanks in advance for your answer. Fred My background is Bsc Accounting and Finance +CFA level 3 candidate.
