You should plan to take the Level 1 in exam this year in June.
If you were a good student and you have time to study 18-20 hours per week from now till the exam (which by the way is in late June this year) then you should be able to prepare well and pass the exam in June.
You should sign up for the Level I Free package on the IFT website and start your studies.
If after 2-3 weeks you are getting along well, then you can register for the June exam with CFA Institute.
You should start with Quantitative methods.
