It is too late to start preparing for the postgraduate entrance examination in June. It takes about 6 months to study hard for preparing for the exam, and it is ok to take the postgraduate entrance examination. Generally speaking, the postgraduate entrance examination lasts for 4-8 months, and 7- 1 1 hour of study time is guaranteed every day. If you usually have a good foundation (the scores of those subjects in the postgraduate entrance examination are above 85), English is OK. Review for 4 months and study for 9 hours every day is enough. This amount of study can basically reach 2 1 1 or 985 from two schools. If it is interdisciplinary, it takes a long time to review, 7-8 months. If the foundation is average, you should start reviewing in advance, about 8 months.
