|I'm starting an IFR course soon and in the middle of the ITA prep.
2 months isn't unfair by any means, if you manage your time properly you will be alright. I suggest that you cancel all social events for those 2 months and solely focus on the ITA.
Most importantly, make a detailed schedule.
I've had the material for 56 days, I've spent 33 of those studying and 23 were offdays/social events (in hindsight, I would cut that in half), etc. I have 32 days left (total of 89 days / 3 months). In 33 days I've covered 30 blocs out of 43 (70%). Keep in mind that I print all the graphics/important pictures, note everything down, review, etc. I'd estimate it takes 40-45 days to really absorb all the material, make clear notes, print important stuff, etc. That would leave you with 15-20 days to review. I don't advise doing much more than 6 hours / day, its a lot of new and complex material (if you have zero prior knowledge). I'll typically do 3 x 2h. 1 to 3 blocs per day is a good pace (some blocs will take 30 mins, others 3 hours, it's hard to quantify).
Also, in preparation for the course, start adjusting your sleep schedule, get rid of bad habits, get in touch with people who are also preparing. In my down time I watched/read a lot about Nav Canada or ATC in general, it gives your brain a break, but in a productive way.
If you want a head start, get familiar with:
-Parts of a plane
-Different types of engines and their characteristics
-Meteorological hazards (wind, snow, rain, clouds, etc.)
-Canadian time zones
-Large Canadian cities and their location on a map
-Alphabetical radio communication (A = Alpha, B = Bravo, C = Charlie, etc.)
Hope that helps.
