look my friend,prediction cannnot be done based on the marks,i have already told that it could vary depending on the level of paper....if the paper was tough then 300 is a good score but on the other hand if it was easier then scoring 300 wouldn't do any good...so i want to say that don't look for the prediction just wait for the results to come out and then we could discuss the possibility of getting the branches considering the last rank admitted .... :)
