Akash, Honestly, it is very difficult to predict the cutoff or the expected ranks of IIT JAM Physics 2020 as of now, but we can make use of previous year trends to calculate the expected rank and cutoff. With respect to the cutoff, it is a big possibility that you would clear the cutoff irrespective of your category as many coaching institutions predict it to be around 16-19 for general category students. However, predicting the rank is a bit more difficult and tedious task as it also depends on factors like total number of candidates and difficulty level of exam which varies every year and we cannot really predict the effect of toughness of this years' paper on the rank. However, looking at past few years trends , you can expect a rank close to 1200-1250, maybe even less than that based on the variables as described earlier. Note that is the General Rank and not the category rank which is very difficult to predict at this instant unless we know the exact number of same category students participating in IIT JAM PHYSICS exam. Also, understand that is only a prediction made on the basis of previous years trends and actual results may vary, however, these predictions do help in evaluating our chances.

Hope this helps.
