You have multiple options, any of which are acceptable. For example:
1) Many will enter just the dates and total hours that they have already completed and include mention in the narrative that they hope to continue in that position for xx hours/wk through y/yy/yyyy. This might be the best approach if you aren't completely sure of your end date.
2) Or you can enter the end date that you plan on, no later than Aug 2021, with the projected total hours (completed + future), but mentioning in the narrative the hours completed as of the day of submitting the application. We understand that "life happens" and something might happen to prevent your completion of the expected number of hours.
3) Or, you could use the AMCAS Repeated feature and enter two date ranges and total hours: the first for completed dates and total hours (ending with the current month), and the second (starting with the current month) for the future date span and projected total hours. Both will appear at above the narrative box. ** Note that you cannot enter a future month or the program will not save it, thus the use of the current month twice, as outlined.
The point is to be transparent about completed vs future hours.
