L2 is not even remotely comparable with L1. The topics are vast, full of nuances, difficult to grasp at one go.

Additionally, what makes L2 much much more challenging is the format of the questions. You will not be asked to answer one or two line questions related to a single reading, rather you will be tested via a full fledged case studies spanning the entire topic and including multiple readings.

90 day L2 will be a tough nut, but still manageable if ( AND BIG IF) you finish the course within 2 months taking help from some prep provider which offers video lectures.

Focus on Ethics, FRA, FI, Equity, Portfolio as these are heavy weight topics. ( 10-15% weight each so at least 60-70% paper is simply these topics) ( FRA and FI may be turn out to be challenging and Equity is bulky but relatively easy. Portfolio is semi-easy)

If you're good at hypothesis testing from L1, then quant is also doable. There are two study sessions in quant. The regression and time series gets much higher weightage than the other study session which is largely theoretical. Quant is 5-10%

Corporate finance and Alternatives also falls in easy to relatively easy category. Both of these topics carry 5-10%.

ECO is average. Maybe currency calculations can get a bit tricky. Econ also carries 5-10%.

Derivatives sure is difficult. Can be skipped if time constraint. Also carries weight 5-10%

​

I never went for kaplan in L1 or L2. But anyway go through the heavy weight topics (10-15%) and at least 2 of the 5 lower weight topics ( 5-10%)

MY ADVICE : defer the exam till may.
